As was pointed out, rcp.statd is supposed to have a large VSZ, but
mount_nfs should not and my swap was getting used up.
mount_nfs will do an RPC clntudp_create for every attempt, but
only a clnt_destroy after a success.
Here is a rather suspicious fix, I have not looked at rpc call

Not expected.

This was it, in normal circumstances the problem would not show up.
I guess I shouldn't be leaving failing mounts around!
