Interrupting mit C-c

[UWN]

Currently, interrupting with C-c just throws an exception. More options would help. Maybe even offer a break (that is, another top level that can be used for inspection). But at least some information, like statistics and the call stack.

Also, I encountered a couple of times when interrupting some clpz computation (that was running for quite some time) the following:

   error(existence_error(procedure,do_queue/2),do_queue/2).

And not easy way to reproduce it...
