I've implemented this a few times, and I always did it by having the 
locker write the current time and the pid at the point of lock. If 
too much time elapses and it doesn't unlock, you can check the pid or 
simply force an unlock.

It's certainly much lighter weight than use file locks. Those are 
slow and not portable.
