It's not possible with the current code base.  I posted a patch a few  
years back that did this....  here we go:

http://lists.danga.com/pipermail/memcached/2004-November/000880.html

It should be easy to apply the patch by hand if it fails to apply  
cleanly out of the gate.  I'm not sure how memcache can survive as a  
store for session information without this patch, but...  See the post  
for details that I won't bore folks with here.  -sc
