Works for me on a local filesystem.
Desktop$ ./gnurr gnarg

However it is true that it doesn't work over NFSv2/v3. The latter is
probably because we use the synchronous NLM calls which block all
signals during the wait in order to avoid state consistency problems (if
the lock gets granted on server after the client was interrupted, then
the administrator gets to clean up the lock).
We can probably relax this requirement a bit, and rely on the CANCEL
call to get us out of trouble.
