I would hesitate to try fixing this without also looking at and possibly fixing
bug #12875. The whole sequence number wakeup thing for condition variables is
fundamentally broken in NPTL and needs to be fixed. Basically the issue is that
the current code is over-engineered to avoid spurious wakeups, but in the
process it suppresses some non-spurious wakeups...
