I downloaded the code, thinking I uploaded the wrong version.

In the programme comments, there is the following:

pickled-sieve.py is an implementation of the Sieve of Eratosthenes
with a twist: when Control-C is pressed, all the tasklets (one for each
prime) and associated channels are pickled to a file sieve.dat.

in the future, if pickle-sieve.py is executed with a file name:

$python pickle-sieve.py sieve.dat

However you somehow missed this while pointing out all these other 'problems'? 


Dalke, I am interested in writing a simple complete non-trivial
example illustrating Stackless Python's 'threads too cheap to meter"
style and the power of pickling. I thought a version of the sieve based on Robert Pike' really cool Newsqueak example would the trick nicely. In
doing so I am not interested in writing complex command line options 
that would greatly increase the size of the code. Or showing every little feature of Python.
