The non-Go code should not change the signal mask on any threads
created by the Go runtime. If the non-Go code starts new threads
itself, those threads may set the signal mask as they please.

If the non-Go code starts a new thread, changes the signal mask, and
then invokes a Go function in that thread, the Go runtime will
