[New-bugs-announce] [issue39182] sys.addaudithook(hook) loops indefinitely on mismatch for hook

[Dutcho]

New submission from Dutcho <dutcho at ziggo.nl>:

When hook is not a compatible callable, addaudithook() will loop forever. At the minimum, a check for being callable should be executed. Preferably, a non-compatible (i.e. signature != [[str, tuple], Any]) hook callable should also be detected.
