I believe we still want to use
mach_port_t port = get_reply_port();
because the caller might not know whether its port is still valid
or not, e.g. when a signal interrupted the RPC and thus we had to
deallocate the reply port to make sure the server doesn't get confused.
In that case the caller will still have the old reply port name, which
we don't want to reallocate since it might already have been reused for
something else.
