No cancel signal in unsafe places.
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.
(cherry picked from commit 1a7f254b4b0590bfab1baa1400705265b1b23b97)
