While is correct as far as it goes, I forgot about VirginRunner and
OutgoingRunner sending the welcome messages. So there are other
mailman processes running in parallel accessing the same config.pck
files so list locking is involved.

I have run a somewhat revised script on both platforms with the
following results:
Cygwin 1.5.19(0.150/4/2) on Windows XP with Python 2.5.1
No loss of members whether or not mailman is running concurrently
(3 of 3 tries with mailman running).
CentOS 5 (Linux 2.6.18-8.1.14.el5) with Python 2.4.3
No loss of members if script is run with mailman stopped.
Lost members if script is run with mailman running on 2 out of 3
tries.
So far, all the failures reported have been with Python 2.4.x and
Python 2.5.1 didn't fail, but this could also be Cygwin and
independent of Python. It would help if others could try this with
Python 2.5.x and report.
Here's the script I used. It is similar to the original, but I
parameterized several things and I added '-a' to the rmlist command.
