[MEDIUM] ensure we don't recursively call pool_gc2() A race condition exists in the hot reconfiguration code. It is theorically possible that the second signal is sent during a free() in the first list, which can cause crashes or freezes (the later have been observed). Just set up a counter to ensure we do not recurse.
