  Modified files:
    lib/libthr/thread    thr_cond.c 
  Log:
  Use a static lock to ake sure pthread_cond_* functions called
  from multiple threads don't initialze the same condition variable
  more than once.
  
  Explicitly compare cond pointers with PTHREAD_COND_INITIALIZER instead
  of NULL. Just because it happens to be defined as NULL is no reason
  to encourage the idea that people can call those functions with
  NULL pointers to a condition variable.
