Zeljan once explained an interesting practical problem he had.

He said the connection per transaction model could be dangerous, specially
in a mobile era where connections are often broken, and thus must wait on
timeout.  This means during rush times, a server can run out of a fairly
limited ephemeral port inventory before abandoned connections start to time

That is a postgres problem though, not the FPC components.
