I'll insist that it should be possible, with the only real conflicts
being what happens when a pool file is created, removed, or renamed.
Since only the thing that removes or renames pool files is
BackupPC_nightly, it's relatively easy to eliminate those possibilities
by controlling when/where it runs. Creating files should just be a
matter of making sure the file creation is atomic with O_CREAT,O_EXCL
(or the old linking workaround for linux nfs bugs) and handling errors
by doing whatever you would have done if the file had been there a
moment before when you looked for it.
