the locking is only meant to be among the N children of a single instance / parent process. You should find the PID here is the parent pid. So I think this aspect is OK.
I have seen fcntl related errors on other OS'es, where APR might use it by default, related to EDEADLOCK being returned when two unrelated threads use two unrelated fcntl mutexes.
