Ok, that fortunate. If it was important, I would have to see if it
would change its relative priority and possibly reschedule my todo
list. Arun@ has done a lot on that front, but it needs more work to
be usable. The more complex the userland problems the more we need
a debugger.

I'll keep it in mind. I probably don't have the time to look for
anything weird, but I might just happen to run into something...
