rpc_pipefs is not currently used in svcgssd.

The short answer is no.  The current sighup processing in idmapd only
attempts to open/reopen the server channels.  (Probably only because
the "normal" system starts the NFS client first, and then the NFS
server.)

It is possible to start two instances of idmapd -- one servicing only
the client, and one servicing only the server.
