In case an OS signal is received will wake the default event loop up shortly so that any registered Python signal handlers registered through signal.signal() can run. Works on Windows but needs Python 3.5+. In case the wrapped function is not called from the main thread it will be called as is and it will not wake up the default loop for signals.

Only does something if called from the main thread. In case of nested context managers the signal handler will be only installed once and the callbacks will be called in the reverse order of their registration. The old signal handler will be restored in case no signal handler is registered while the context is active.
