	There are two proposals for this currently (everyone flog me for not  
putting this on the wiki and pointing to it):

	1)  Regex (or prefix) clearing.
	2)  Tagging (and tag clearing).

	Both work in a similarly.  Here's the description I wrote of the  
wildcard delete mechanism:

	http://lists.danga.com/pipermail/memcached/2007-July/004711.html

	The same thread goes over tags a bit, but effectively, you'd be able  
to tag the key with the server name and delete by the server name tag.
