Aha! So maybe we should reconsider whether mwh's removal of the filename interning in the compiler should be reverted.

I just looked at the sizes of the four largest .pyc files wrt. to this change (ie. the one generated before 2.312, and the one generated after):

              before            after

pydoc 84711 91263 cookielib 57353 57353 pickletools 55862 57038 tarfile 54074 58974

So the patch does cause a size increase (and likely also a slowdown because of the extra memory allocations at startup). Whether this is relevant or not, I don't know.

I think I would prefer if a different mechanism was found to account for the change in references during an import, e.g. by taking the number of interned strings before and after the import operation.
