Modified files:
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.
