when a search fails for a single url because the snippet cannot be generated, then the url reference is deleted from the index. This mechanism was redesign and enhanced. The process now also writes into the work tables into the table searchfl to prepare a re-indexing mechanism.

- added use of LookAheadIterator which should prevent mistakes when coding iterators with embedded iterators
- added a fail-safe reaction in case of database corruption using iterators over database elements (no interruption then)

- crawl lists for each domain now uses a HandleSet which should use less memory than LinkedLists
- but: fill more entries into the domain lists (all available entries)
- fixes to selection criteria (best domain selection)

- no direct deletion of referenced during search (shifted to time after search)
- bundling of all deletions for the references of a single word into one remove operation
- enhanced remove operation by caring that the collection is stored sorted (experimental)
- more String -> byte[] transition for search word lists
- clean up of unused code
- enhanced memory allocation of RowSet Objects (will use a little bit less memory which was wasted before)

- removed usage of URL-Caches which could have been a memory leak
- removed unused classes and methods
- removed not necessary synchronizations
- added synchronization hacks where possible
- fine-tuned crawling speed to prevent IO of balancer
- fixed a bug in IODispatcher that may have caused that no merges were done
- reduced number of parameters in very often called methods (compare methods)
- reduced complexity of data structures of now massively used HandleSet class
- reduction of new String() and getBytes() usage / new methods to support this transition

The result should be a less usage of new String() and less memory usage (since a String-encapsulated byte[] has 40 bytes overhead)
