This script will "fix" your problem too, I hope. We think it fixes ours. 
:> I assume it tells libc to not use futex(). I wish the linux community 
would get on the ball and make a nice regression test for this bug so it 
never pops up again. Right now my test is "Does the CANVAS gui work?". 
Maybe your test script is better for that. :>
