in case of "object too large for cache" error; spymemcache goes for closing and reopening memcache connection.

What version of the product are you using? On what operating system?
2.6 , 2.10.4 (centos,fedora)

Tell me more...
spy memcache throws error "object too large for cache" in case of object size 
is large. besides, it closing and reconnects the memcache connection. which i 
guess should not be like that. 

In case of high loads, this closing and reopening connection throws Timeout 
exceptions of other async get calls.
