   have also consume a signal in the waiters group.

   It is essential that the last field in pthread_cond_t is __g_signals[1]:
   The previous condvar used a pointer-sized field in pthread_cond_t, so a
   PTHREAD_COND_INITIALIZER from that condvar implementation might only
   initialize 4 bytes to zero instead of the 8 bytes we need (i.e., 44 bytes
   in total instead of the 48 we need).  __g_signals[1] is not accessed before
   the first group switch (G2 starts at index 0), which will set its value to
   zero after a harmless fetch-or whose return value is ignored.  This
   effectively completes initialization.


   Limitations:
