Wouldn't a sensible approach be to discard the linecache when you've finished generating a traceback? You're not likely to be generating tracebacks often enough to be worth keeping it from one to the next.

The linecache is also used by the warnings module. I think the sensiblest approach would be to limit its size (LRU-style).
