Conceptually I think they should all go in add-on(s), however I suspect that when an exception is thrown inside a signal handler, cleanly unwinding the call chain will need special support in the core. That's not to say that methods for setting the signal handler needs to be in the core though, just the low-level code that receives signals and arranges not to leave a (broken) partially-formed call frame in the chain while setting up a call frame to invoke the handler function. -Martin
