Yes it can and should. But keep in mind PHP leaks like a broken
umbrella so normally each PHP process is restarted every N requests,
thus dropping any connections. (N is normally 10000 or something).

Even though this really is out of topic for this list :)

Quick question and tip: Why are you using pconnect? It's almost always
a bad idea. Setting up a TCP connection on an internal network is
really cheap in comparison to connecting to other networks. If you are
connecting to an outside network, connection latency might become a
problem and then pconnect is there to ease the pain.
