2009-05-15Fix change to prevent cancel signal in unsafe places.Ulrich Drepper
The bits tested to decide when to delay the return when switching off async cancel mode were wrong. Fix that. Also close a race condition in pthread_cancel where the bit indicating the cancellation is unconditionally set even if the cancel type might have changed.
2009-05-15No cancel signal in unsafe places.Ulrich Drepper
When disabling async cancellation we cannot return from the function call if the thread is canceled. This happens when the cancel bits have been set before async cancel is disabled but the signal hasn't been sent/received yet. Delay for as long as necessary since otherwise the signal might be received in an unsafe context.
