719
720A simple form of RPC - sends a message to the given C<$port> with the
721given contents (C<@msg>), but adds a reply port to the message.
722
723The reply port is created temporarily just for the purpose of receiving
724the reply, and will be C<kil>ed when no longer needed.
725
726A reply message sent to the port is passed to the C<$callback> as-is.
727
728If an optional time-out (in seconds) is given and it is not C<undef>,
729then the callback will be called without any arguments after the time-out
730elapsed and the port is C<kil>ed.
731
732If no time-out is given, then the local port will monitor the remote port
733instead, so it eventually gets cleaned-up.
734
735Currently this function returns the temporary port, but this "feature"
736might go in future versions unless you can make a convincing case that
737this is indeed useful for something.
