FWIW, with a recent GCC on Linux you can throw exceptions from signal handlers and they will be correctly handled (this is required to support Java and I think Ada as well). You need to compile with -fnon-call-exceptions or -fasynchronous-exceptions. These have been available for quite a while but were very buggy in C and C++ until recently.
Maybe one day they get the idea, that not every idea from microsoft is so bad.
Async exceptions do have their use; the problem is code must be carefully designed to deal with async exceptions so you do not want these to be enabled by default. Also they have non-trivial costs (async unwind tables can be very large). -- gpd
