protected void valueRemoved(K key, V value) {
		// stub for subclasses
	}
Called when an item is being removed from the cache. This method is for use by subclasses 
that need to do more processing on items as they are removed, such as releasing resources.
<P>
Note: this method will always be called from within a synchronized block. Subclasses should
be careful if they make any external calls from within this method.

@param key The key of the value being removed
@param value the value that is being removed
