I put a branch that should fix the issue up at
http://people.ubuntu.com/~mvo/bzr/apt/tagfile-mmap-fix/

I send a patch to James asking for testing and will upload it to
experimental (along with some other fixes there). Once I got positive
feedback on the patch I will merge it into the sid version of apt and
upload.

The new version will use MMap if possible in tagfile and if not fall
back to the old implementation.

Thanks,
 Michael
