I took a look at the patch. It looks fine and I see, that it contains
fixes for the latest questions in the thread.

I think we should provide a test module for this feature, that will
serve as both test and example of the use.

This is a feature for extension developers, so I don't know where we
should document it. At the very least we can improve comments. For
example, describe the fact that custom signals are handled after
receiving SIGUSR1.
