I'm not sure I follow that one. Any apps that had the semaphore open
before checkpoint still have it and it behaves as it should. Any app
that opens the semaphore after checkpoint works just fine as well. The
only problem is between two apps, one that opened it before and one that
opens it after the c/r cycle. The semaphores are no longer "the same".
But, as I said, that's not something we can solve without the unlinked
bits (which aren't finished yet). Aaaand, as I said, this doesn't work
for linux-cr yet for other reasons, so nobody is asking Oren to apply
this set yet anyway.
