A traditional web-server application forks a new process for every request 
with 'fork' (man -s2 fork). Question how to use memcached_pool with 
processes. 

With processes, the memory is isolated between the processes. After fork, 
the whole memcached_pool is doubled to a new process. Freeing the memory 
after the request is served and the child process is closing, causes an 
instability (was it an illegal close or a segfault). In addition, copying 
the pool to each client does not seem to be reasonable.

The solution in use now is to use 'memcached' instead of 
'memcached_pool_pop' to get a new connection (allways to the next client 
process). It is recommended in the ~/doc/protocol.txt that the memcached is 
used with multiple open connections and not to open a new connection every 
time. 

What is the best practise with 'fork'?

How can I make my server application faster? Is it possible to use 
'memcached_pool'? Is it somehow possible to just 'dup' the memcached socket 
connection somehow or is dupping the socket connections this way possible 
at all? 

With best regards,

Jouni
