When TPL::REPL is unavailable, the debugger kills the entire application

Ole Myren Rohne reports:

I'm playing with AbclScriptEngine (with Electric VLSI) and found a tiny problem with config.lisp: EXT:MAKE-THREAD should be THREADS:MAKE-THREAD.

which is already solved, but continues:

Unfortunately the problem was unnecessary hard to debug because in the absence of TPL::REPL the debugger ends up quitting the entire application. I'm wondering if in that case it would be more useful to throw a Java error, eg like SYS::%DEBUGGER-HOOK-FUNCTION?

That's what this ticket is about.

This issue is fixed in 0.24: (QUIT) doesn't call EXIT anymore, but instead throws a Java exception.
