And this improves the scaling of the cache stating overhead, but we may well want to fix this more fundamentally - e.g. by linking the cache ownership into the import system somehow, so that when a file is reimported, the cached source is automatically evicted, and format_stack etc have no need to stat at all.

I tested this with the following script in timeit:

import traceback

def recurse(count):
  if count> 0:
    return recurse(count - 1)
  return traceback.format_stack()
