Maybe, but I'm really fucked up...
Saying "bad style" might help to keep people from
producing more problems :-)

Full stack analysis is really hard at this stage.

On the other hand, I think I have a work-around
that might work in most cases:
Right now, I install kinda "stack root", whenever
I see an initial frame, that is one with no f_back.
Maybe that's just bad. I saw myself moving 8kb of
stack away in the context of Tk. this is obviously
a large "installation" on the stack.
I might instead enforce the user to start a new
"root", manually. This would then no more start
automagically, but "by hand", on top of any stack
stuff that I better should not touch.

what would you suggest? -- ciao - chris
