FileLock.steal(): New method which just basically writes a new PID
into the lock file. USE WITH CAUTION. Necessary because in the new
news/mail gating code, the parent acquires the lock, and if
successful, the child will steal it from the parent and then unlock it
when done. This should be safe, with a very small race window, if
any.
