I've been getting quite a few processes spinning (chewing up all
available CPU) recently.  These processes will die with `kill -9', but
do not respond to any other signal.  The problems started for me when
I upgraged (full release) around 1.6U, and continue through 1.6W
(kernel only updated) - before that, I wasn't very up to date anyway.

The following 3 line program demonstrates the problem:

    int main(void) {
      int z = 1 / 0;
    }

I'm a bit stuck for ideas on how to debug this further!

Tim.
