Pre-existing, and not changed here (so this patch is still good), but we probably ought to start making the lease manager reserve backing files as readonly, rather than limiting the reservation to just the top-level file. (Did I already mention this in an earlier review?) At any rate, I suspect that we are leaking reservations when we do snapshots and/or commits, although I haven't played enough with the lock manager to actually prove or disprove that.
