Can it not be done by wrapping every thread (even the primordial one)
in a conventional exception catching block, which then generates a
normal exception handler which calls to a continuation up in the
dynamic scope of the catching block, thus unwinding the stack? Then
it can just catch the exception and report exceptional thread
termination, or in the normal course of events cleanly shut the
thread down.

Should be an easy fix, no?
