But I realized I never got a more fundamental question answered: when does a signal handler written in Haskell run? Is it like C, in that it

I'm not sure it *does* run. That is, I don't think a Haskell-based signal handler is even possible. When I talk about Haskell's signal handlers, I mean C handlers within the GHC runtime.
