No, wasn't confused over that. Was confused over something else though :-)

That's pretty much right on the mark, and the heart of the problem I
suspect.
So this means we'll have to pull relHash out of the shared FreeSpaceMap
structure and make it a variable in it's own right? [Same goes for lockHash
and proclockHash in the LockMethod structure reference by "LockTable (lock
method table)"]

Keeping this firmly in mind, trust me.
