That would be great. The first thing I'll be trying (once I get back
to it) is simply skipping the crasher I think is the main cause of the
instability (the compiler recursion one). I already deliberately dodge
the two crashers that are known to cause infinite loops, skipping one
more wouldn't be a terrible outcome.

I need to bug Barry about his PPC buildbot as well. It seemed to be
surviving even after I had cranked the expression size in the compiler
recursion crasher to absolutely ridiculous levels, so I'm wondering if
there may be something different about the way PPC handles the stack.
