Spawning a new thread to handle a signal is much better than preemption: you then have no concerns about async-signal-safety that aren't plain old thread-safety

Spawning a new thread to handle a signal is much better than preemption: you then have no concerns about async-signal-safety that aren't plain old thread-safety concerns. I'd much rather have thread-safety constraints than async-signal-safety constraints.

Sort of. At least you can mask signals. I agree that threads are probably better overall, but I don't think it's a huge difference.

Linux can do that as well, see SIGEV_THREAD.

  Only for AIO, which few use.

    You can spawn a thread manually and use the POSIX sigwait() function.

      That won't stop the process-wide registered signal handler working and it won't do anything about being able to reliably handle synchronous signals.
