	* CacheEntry.cs,CacheExpires.cs,ExpiresBucket.cs,
	  Cache.cs : Fixed deadlock issues, fixed
	  items not correctly being flushed, fixed update
	  of item when expiration has been updated more
	  than 1 min (placed in wrong bucket),
	  fixed deadlock during cache callback when item
	  is removed due to expiriation.

	  Rewrite of locking handling in Cache class, leading
	  to better performance and less bugs.

	  This rewrite is due to a number of bugs found
	  in the output caching during load (leading to memory
	  leaks and deadlocks)
