Connection timeout for session handling

[giac]

Hi,

At the moment it's not possible to set the connection timeout when using memcached as session handler.
So if the memcached server is down the request hangs for ages waiting for the connection.

Could you please add this?
It probably needs to be a parameter in the ini file, something like:
memcached.sess_connect_timeout = xxx

In my opinion the timeout should be around 3 seconds by default.

Thanks!
