Most simple and important example I have right now is the
well-known issue that the VM will freeze indefinitely if you
input a long running calculation, e.g. x := 100000
factorial. The interrupt key doesn't work, usually. Newbies
like me, like to experiment, and if the VM freezes with
every typo, then its hardly worth using.<br>

<div>This is interesting because it does *not* freeze in my
Qwaq-derived work image. Here the interrupt key works
perfectly with no delay. I'll see if I can investigate.
Andreas, do you recall doing anything to the debugger to
fix issues like this in the Qwaq system?</div>

Nothing I can recall. Also, when I try interrupting 100000
factorial in a 4.2 image with either a Teleplace or OpenQwaq VM I
have no trouble interrupting anything. So it doesn't look like
it's an issue in the image that is causing it. Wonder if there's
anything changed in the support code perhaps...<br>
