I would propose that you forward a patch to Linus - either the one you 
have in your tree or the v2 that I've just posted.
With stock 2.6.35-rc3, my semtimedop() stress tests produces an oops or 
an invalid return value (i.e.:semtimedop() returns with "1") within a 
fraction of a second.

With either of the patches applied, my test apps show the expected behavior.
