dualmetafix_mmap.py
Hi AcidWeb,

Attached is a quick and dirty revision of my original dualmetafix.py to use mmap. I called it dualmetafix_mmap.py. It passes my check with a small sample file.

But Please check its memory usage against your 400 Meg file and see how bad it gets. It should stay near just a few meg over the file size. If not, we should probably move to complete fileio operations with seek and read/write in chunks.

Please let me know what you see.
