	Of course, but I don't want to do this. The problem is that client
is querying portmap over TCP and from privileged port. By changing this
we can use twice as much mounts in the TIME_WAIT period. We may also
force mount to query mountd over UDP, but I don't know how to do this.
-o udp is probably for nfsd traffic, isn't it?
