Yeah, that's an issue.  When you've got, say, 50 memcache servers, 
though, and one fails, you're only getting 1/50th of those queries 
passed to the DB.  So it's not (at least, for us) that big of a deal. 
49/50 queries to memcache is still nice.

Definitely should be an option.  I'm not trying to suggest that our 
needs are everyone's needs - but I'd be surprised if they weren't 
*someone* else's needs. :)
