I don't believe that's a good idea: Locking would no longer be atomic,
and you can get deadlocks that way.
I don't think that it's that big a problem. If the second lock fails,
you release the first lock and wait for a bit. Then the worst that can
happen is a livelock.
FWIW, procmail (on Linux at least) uses both dot-locking and kernel
locks (can't remember whether it's flock, fcntl or lockf).
