I dount see how this is any better, with a suitable bug you can still
have a neverending loop, right? I was thinking more something like this:

count = 100;
do {
    ....
} while (count--);

That way the won't be more than 100 loops no matter how many bugs there
are :) Of course I have no idea what would be a good value for count.
