I don't like where this is headed. Converting signals into 
exceptions is a bad idea.

In a multithreaded program, which thread should get the exception 
thrown? The main thread? Every thread? What if main already 
terminated?

The InterruptException must be anticipated in lots of places and 
most people will forget about it.

Basically, the issues are very similar to killing threads [0]. 
Throwing exception anywhere without any relation to the code at 
that point is a recipe for disaster.
