>Description:
	libc RPC logic does not handle file descriptors larger than FD_SETSIZE.
	for instance, lib/libc/rpc/svc.c:xprt_register() silently ignores
	sock > FD_SETSIZE.  other functions behave like so.
	the problem exists in NIS and other RPC userland code (outside of
	library) as well, as fd_set manipulation is exposed as API.
>How-To-Repeat:
	code inspection
>Fix:
	it would be difficult as fd_set manipulation is exposed as API
	(such as svc_fdset in /usr/include/rpc/svc.h).
