It would be silly to pass many fds.  fds are scarce resources and you 
don't want to get into a position where you're queuing fds.  If a 
management tool wants to send an fd, it should issue the monitor command 
that needs the fd along with the fd via SCM_RIGHTS, and then wait for 
that command to complete before issuing another command that needs an fd.
