Hi Mike,

Yes, it should hang forever. You have asked it to backup a file that
another process has issued a mandatory read lock on, apparently.
rdiff-backup is doing precisely what you asked it to do. Unfortunately,
it is being stymied by another process you are running.

Either that, or terminate the process that is holding the lock (havp)
before running the backup.

If rdiff-backup were to try and ignore this on its own, it would have to
test for the presence of a lock on *every single* file on your
filesystem. This would cause significant slowdown.

Patches to implement this as an optional feature would almost certainly
be accepted.

Perhaps that's the reason that the Linux mand option is non-POSIX...
