    lib/libpthread/sys   lock.c 
  Log:
  Change the spin lock logic to a reasonable one.  We should spin when
  the lock is held by other thread, but not when nobody owns it.  According
  to deischen@, this part of code will never be hit in our threads
  library, since it does not use locks without wait/wakeup functions.
