* Does now keep one or two empty areas around, so that even in case of
CACHE_DONT_LOCK_KERNEL_SPACE memory can be provided as long as pages are
available. The object cache maintainer thread is used to asynchronously
allocate/delete the free areas.
* Added new debugger commands "slab_meta_chunk[s]" and improved the existing
ones.
* Moved Area::chunks to MetaChunk.
* Removed unused _AllocationArea() "chunkSize" parameter.
* Fixed serious bug in _FreeChunk(): Empty meta chunks were not removed from
the partial chunk lists and could thus be used twice.
