Command used within Python Module causes memory leak?

[Eric Thivierge]

Hello again,

Just wondering if anyone has experienced memory leaks when using 
commands within Python modules that have been imported? Doing some mesh 
merging and attribute transfer within a method of a class I created, and 
the memory sky rockets and takes forever. However when I run the same 
code in the script editor outside of the python module, it works without 
crazy a memory leak and finishes within a good amount of time.

I'd like to mention that I'm setting the undo stack to 0 before running 
the code for each test.
