Most all the code I've worked with assumes that fcntl locking is available
if fcntl is available. If you need to support pre-POSIX systems, you
should fall back on flock and lockf in that order, but these days, it's
pretty safe to assume that any Unix system has fcntl.
I don't know anything about Windows in this area.
