Currently only socket connection is wrapped in a timeout.  After that  
the socket is left open.  Every socket access used to be wrapped in a  
block for mutual exclusion, but I've removed the blocks because it  
chewed up a significant amount of the time spent in the client.

I don't think I'll be adding another block invocation to the code,  
but adding a call to #select on the socket to check for writability  
in #cache_get might help.
