Open a lock file and try to get an exclusive flock or a write fcntl lock.
if the attempt fails, the program is already running. Otherwise this is
the running copy; keep the lock file open: that keeps the file system
busy, and on process termination, for any reason whatsoever, the kernel
frees the lock for you.
