I would try this:

trackTable = track.table  (just something that is clearly different

where trackTable is just a string. I'm a little paranoid when coding,
so I would probably add something to check the type, then a
str(tackTable)... but, that's probably over doing it ;)

I think the issue really just the name, where this would be fine in
any py script, here we have no control over how the table_name gets
validated (unless as mentioned above, you change the code to change
the behavior), and we know that the code has a strong insistence on
uniqueness for the table names it creates.
