# When con1 does UNLOCK below this will release either con2 or con3 which are
# both waiting on LOCK. At the end we must first --reap and UNLOCK the
# connection that has been released, otherwise it will wait forever. We assume
# that the released connection will be the first one that has gained the LOCK,
# thus we force the order here - con2 does LOCK first, then con3. In other
# words we wait for LOCK from con2 above to be exected before doing LOCK in
# con3.
