>Description:

When calling pthread_cond_timedwait(), it doesn't honour its abstime but 
immediately returns. Even specifying values in seconds does not make a 
difference; it just returns.

pthread_cond_wait() eventually dispatches to _lwp_park() that obviously 
returns immediately.


>How-To-Repeat:
try a pthread_cond_timedwait() with a timeout of few seconds and whatever 
you pass, it returns immediately.

Unknown
