One thing I noticed that if all 3 mutexes are available, fcntl()
will be chosen (since it's the last). The rub is that fcntl() is
slow and expensive (well, it _can_ be) on systems running NFS.
I would suggest the preferences be:
semget()
flock()
fcntl()
thus fcntl() is chosen only as a last resort... Make sense?
