Interesting. I have played around with some external functions
to allow pickling of a zope execution. But as I remember, it was
a lot of hacking to avoid pickling of certain zope structures.
Maybe I can dig this up.
I ended up with a pickle that could be restarted, displaying
a counter on a web page.
I think I had to make sure that the tasklet was really removed
between responses. No idea if there is much future in this...
