[Bug nptl/417] pthread_mutex_timedlock can sometime consume a futex_wake signal and return a timeout -- leading to a hang.

patch attempt to correct the bug for i486 architecture

Here is an attempt I made to correct the problem. I'm not sure if there are no
undesirable side effects. The basics is that if the futex was in "1" state, we
change it to "2". The only problem I can see is that we will eventually enter
the kernel on a mutex_unlock where it would not be necessary....
