I guess it depends on your definition of process. DAV locks are
supposed to be capable of being held for an extended time. I might 
want to lock a resource, edit it for a while locally, then push the
result back and unlock it again. Are you suggesting this all has
to be done by the same OS process? What happens if the power goes
out and my PC reboots? Or perhaps you expect the client to cache

In my case, it is the same client I'm using to lock and unlock and
I'm presenting the same credentials to the server. Its a low
level test program, so I would have thought being able to unlock
a resource of which I am the owner would be reasonable.
