On your suggestion, I’m not sure that’s exactly what we want.
Even though we can ask user to do signal chaining themselves, I don’t think it’s necessary. I don’t think we should be promoting the broken design of posix signals around. ;)
Another thing is that this design is not portable and exposes a bit too much of mono internals.
What about this: https://gist.github.com/569e860dd7e73bde0d8d098f95143662
It probably won’t compile as I normalized the signature of mono_handle_native_sigsegv with other similar functions.

This is not about exposing signal handlers to managed code, the signal handlers we want called are always in native code.

Something like this: https://gist.github.com/rolfbjarne/6aab59c1609f33402d195f9c34e9f99b?
