[Stackless] Fwd: deepcopying (pickling) channels

[Christian Tismer]

Haha,

well, this is something for WingWare. Or you can work around it.

When certain things happen, like pickling, the Wind IDE needs to
return the original objects, by either releasing its hooks, or
by pretending they do. No idea how difficult that is.

Maybe you can special-case this, walk the frames tree of the tasklet to 
pickle
and construct a fake one that has references to the hooked things unwrapped.

Well, that's not me ;-)
