[Stackless] Fwd: deepcopying (pickling) channels

[lars van Gemerden]

Thank you Chris,

I am doing something else now but will be testing/using this asap (a lot on
my plate).

Has anyone checked what the behavior of non-stackless python is (with
and/or without Wing debugger). I think that if possible that should be the
situation to mimic and should give an indication who is best positioned
(Wing and/or Stackless) to do the final fix.

Cheers, Lars
