I have an implementation of fcntl(F_SETLK/F_SETLKW, F_GETLK, ...)
for those that want it. I hope to have it on tsx-11 shortly, but
until then, send me email if you want it.

I have also submitted it to Linus to be included in the next release.

The implementation is almost complete. It includes weird cases like locking
a big chunk and unlocking a piece in the middle. What's missing are

- deadlock detection
- mandatory locks

I view both of these as being of dubious merit, so do not intend to
implement them any time soon. HJ Liu is looking into implementing deadlock
detection.
