Joe, I read your first email last night, and mulling over the
possibilities, concluded that the problem was just as you have
diagnosed. I awoke this morning ready to fix it, and found you already
had! I'll apply the patch today...<br>
<br>
Thanks.<br>

parallel=True was implemented.
Issue and provisional patch that seem to work for me here:

<pre wrap="">Does anyone have a recipe of getting coverage.py to work across a fork()?
I was trying to use coverage 3.3.1 with python 2.6 and
multiprocessing, and couldn't figure out how to get it to trace the
child.
Attached is a simple test program to illustrate behavior and show
things I tried.
Is there another way of doing this I didn't come across, or is this
something that needs to be hacked into coverage?
Thanks!
Joe
