another unique feature of Stackless is pickling/unpickling of tasklets
and many other python types. This feature is essential for many
applications and probably needs some additional C-code besides 'tealet'
/ '_continuation'. That said I like your proposal, but I doubt that we
have enough man power to implement it.
