This is pretty much what I was hoping it would do. I've emailed Franz
technical support about what the behavior is in this scenario. I
guess I won't be to surprised if they don't want to promise any
particular behavior in this area. I'll look into the fork method,
should have thought of that before, that would at least give us a
working solution on Unix platforms (which is all I need personally).
How does Slime feel about platform specific functionality like that?
