I'm sort of confused here: are you suggesting that if a LOCK request
comes in on an imaginary file path, that we (1) create an empty file,
(2) create an entry in the locks-table? Or is it sufficient just to do
(2)?

Okay, I think this was my original question. If process A locks an
imaginary path, then process B tries to delete a parent dir *before*
process A does a PUT, then process B's request should fail, right?
That's what your explanation sounds like to me.
