OS: All
Status: NEW

There is a race condition that may be triggered causing the thread to sleep
longer than desired. It is triggered if the thread is preempted after
calculating "__t - _Clock::now()" (__mutex_hase:353) and before getting the
system_clock time in wait_for (__mutex_base:382).
Observed in revision 217271.
