The cause for this problem could still not be found, but the effect
is handled much better. The NURL-pop will continue automatically until
it found a hash that can be found.

- better memory allocation for FlexTable indexes
- splitting between static index and dynamic index (only the dynamic part must grow)
- to enable a merge-iteration of new splittet index, a huge number of classes needed to be adopted for new iterator classes
- added new iterator classes that support cloneable iterators
- adopted all iterator classes to implement cloneable itarators

- each cache can now allocate as much memory as is available
- no more fixed limits
- replaced old performance memory monitor by new one
- added supervision methods as static functions into the classes that provide cache functionality
- steering of ram allocation is done with two simple limits that are ram availability-relative

too large collection arrays are now avoided. By default, the biggest
collection index is 7. larger collections are dumped into a commons
directory, but cannot yet be used. Bevore doing a dump, the collection
is splittet into a part which has only root-references, and stored back
to the collection; the remaining part goes to commons

- robots.txt is a servlet now
- no need to rewrite the whole file each time a section is added or removed
- user-defined disallows, added manually, won't be overwritten anymore
- new config-setting: httpd.robots.txt, holding names of the disallowed sections

- permanent cache flush is switched off. The optimized cache flush
works better if it is a large number of collections that is flushed
together
- the flush size can be configured instead the flush divisor. There is
only one size for all flushes
- collection records that shall be removed during collection transition
(jump from one collection file to another) are now not really removed
but only marked in RAM. add-operations to the collection use these
marked collection spaces
- index bulk write operations are now separated for each file of a kelondroFlex

- collections are now hand-over as collection lists to collection index for merge opertations
- collection index lists are separated into 'new' and 'extend' lists
- lists are written separately
- write operations are done into array sets and array indexes. These are now serialized
- write operations into index files are sorted by index;
that means that a R/W head does not need to go forward
and backward, only forward
More enhancements are possible

warning: an interface-change had been neccessary:
- remove(String, String) has been renamed to removeAll(String, String), because it removes all path-entries for the specified host
- remove(String, String, String) has been added to delete only a path-entry

- new domains now get a chance to get crawled early
- less IO operations
- new balancing method
- better dump order at shutdown time
- bugfixes regarding not found url hashes (no more superfluous cache kill)
- domain access time is now shared over all balancer stacks
- viewing the stack does no more disturbish the balancing algorithm that much
- intelligent selection of best next domain using domain access times
- extra double-check (to double-check the double-check)

redesign for better IO performance
enhanced database seek-time by avoiding write operations at distant
positions of a database file. until now, a USEDC counter was written
at the head-section of a kelondroRecords database file (which is the
basic data structure of all kelondro database files) to store the
actual number of records that are contained in the database. Now, this
value is computed from the database file size. This is either done
only once at start-time, or continuously when run in asserts enabled.
The counter is then updated only in RAM, and written at close of the
file. If the close fails, the correct number can be computed from the
file size, and if this is not equal to the stored number it is a strong
evidence that YaCY was not shut down properly.
To preserve consistency, the complete storage-routine had to be re-written.
Another change enhances read of nodes in some cases, where the data-tail
can be read together with the data-head. This saves another IO lookup during
each DB node fetch.
Includes also many small bugfixes.
