Dear Dmitry, Bryan and Philip,
Thanks for the suggestions. I poked around the dictionary descriptions
and fiddled some more but couldn't find any obvious error. I agree it
does seem odd that a 50 kb dict should fail. Eventually, I tried

You could be right. I'm not an expert on python memory management. But
if it isn't memory fragmentation, then why is it that I can create

I am getting a MemoryError when creating a dict in a long running
process and suspect this is due to memory fragmentation. Any
suggestions would be welcome. Full details of the problem are below.
I have a long running processing which eventually dies to a

I am having some issues with the subprocess module and how it
interacts with win32security.ImpersonateLoggedOnUser. Specifically, I
use the latter to change users but the new user does not seem to be

Dear Experts,
How do you pass the -c option to setup.py install? Specifically, when I try
to install zope.interfaces version 3.3 from source on a windows machine, I
get a message about using -c mingw32. That works fine for setup.py build,
but it does not work for setup.py install.
Note: I would

After some fiddling, I figured out that you can put the following two lines
in setup.cfg:

compiler=mingw32
It would be nice if you could somehow pass

Is there a good way to choose/assign random dynamic port numbers in python?
I had in mind something like the following, but if multiple programs are
generating random port numbers, is there a way to check if a given port
number is already taken?

Is there any hope of a parallel processing toolkit being incorporated into

Dear Experts,
I love the pickle module, but I occasionally have problems pickling a
function. For example, if I create an instance g of class f and assign
g.xto a function, then I cannot pickle g (example code below). I know

explicit information when you do a compile time call to setattr?
For example, imagine that I have the following block of code
