creating generators from function

I see I am misunderstood. The example was contrived, and it seems, incorrect.

I simulate threads, using generator functions and a scheduler.

My implementation lives here: http://metaplay.com.au/svn/LGT/LGT/nanothreads.py

If the same functions were to run inside a normal thread, they would
need to loop forever, rather than yield None on each iteration. I see
now that replacing return with yield won't work, a yield instruction
needs to be inserted somewhere.

I guess this changes my question to: Can I convert a function
containing an infinite loop, into a generator which will yield on each
iteration?
