I haven't said they're doomed, although I have said that people who
want to use them are on their own.  I think the latter is simply an
obvious truth, since (a) multiple interpreters have been entirely
unexercised by the Python test suite ("if it's not tested, it's
broken" rules); (b) Python developers generally pay no attention to
them; and (c), as the teensy bit of docs for them imply, they're an
"80% solution", but to a problem that's probably more sensitive than
most to glitches in the other 20%.

I've also said that Mark's thread state PEP explicitly disavowed
responsibility for working nicely with multiple interpreters.  I said
that only because that's what his PEP said <wink>.
