I would appreciate comments before putting it in the Stackless

As style comment only, the ()s are not usually written in 'while' and
'if' terms. That is, lines like
while(True):
if (flag):
are typically written
while True:
if flag:
I believe you need to make
fd = open('sieve.dat','w')
be "wb" so that it can work on Windows. I have not tested this.
I don't know if you have pedagogical reasons, but I prefer to write
def filter(prime, listen, send):
while (True):
i = listen.receive()
if (i % prime):
send.send(i)
as
def filter(prime, listen, send):
for i in listen:
if i % prime:
send.send(i)
and
def counter(c):
i = 2
while (True):
c.send(i)
i += 1
as
import itertools
def counter(c):
for i in itertools.count(2):
c.send(i)
or even
import itertools
def counter(c):
c.send_sequence(itertools.count(2))
I am having trouble making your demo work (after loading the image it
still starts from the beginning), but I suspect that might be to my
now years out of date Stackless.
Cheers,
Andrew
