Thomas,
here is a patch that fixes the -EINTR problem and a fix for Dinakar's
simple futex deadlock test program. When Esben's new deadlock detection
is ready I plan to use it for robust futex deadlock detection, both simple and
circular deadlock detection.

The stats are nice. I'd prefer a patch associated with them :)
