php memcache client hanging on large write

[Jon Drukman]

we're using the ryan dean php memcache client, and it's exhibiting some 
weird behavior with large items.  i don't have hard numbers but i'm 
guessing if the datum to be stored is > 128K, it basically hangs forever 
while writing to the memcached server.  i straced a hanging apache and 
found it would reliably get stuck in send(...) while writing a big item.

the daemon itself is still able to serve other requests while this 
happens, so i'm guessing the problem is client side.

anybody encountered this?  ideas/recommendations?
