"This was observed in production code, where exc_info 
tuples are saved for re-raising later to get the stack-
appending behaviour tracebacks and 'raise' perform."

I would like the traceback object so that I can re-raise the error. I can stringify it as tim_one suggests, but that can't be used with 'raise' and 'try','except' later.

It is not important for my application to have all the references that the traceback object contains, which is what is causing the massive memory requirement. If I could replace the exc_info()[2] with a traceback look-alike that only held file, line, etc information for printing a standard traceback, that would solve this problem.
