This would call the function C<Some::Function::name> with the string
C<myownport> and some additional arguments.

=head2 MONITORING

Monitoring the connection itself is transport-specific. For TCP, all
connection monitoring is currently left to TCP retransmit time-outs
on a busy link, and TCP keepalive (which should be enabled) for idle
connections.

This is not sufficient for listener-less nodes, however: they need
to regularly send data (30 seconds, or the monitoring interval, is
recommended), so TCP actively probes.

Future implementations of AnyEvent::MP::Transport might query the kernel TCP
buffer after a write timeout occurs, and if it is non-empty, shut down the
connections, but this is an area of future research :)
