Right. Can you try this patch and see if it solve that problem?
* Add exit handler in if-up.d/mountnfs to make sure the lock directory
is removed when the script is interrupted.
* Print message when refusing to mount directoryes because the
lockdir exist.

I'm not quite sure how to best handle the issue with NFS mounting and
several network interfaces, but thought it should be possible to at
least handle the interrupted script case better.

Yes. This will disable the locking completely. The mkdir command
will no longer fail when the lock already exist, and two instances of
mountnfs might run at the same time.

I agree that some message should be printed. I'm not sure about the
exit code, so I leave that as it is.
