Johannes, have you *tried* the patches?

I really don't think you have. It is completely unnoticeable in any
normal situation. The two cases that it's noticeable is:

 - a full fsck is noticeable slower

 - a full non-local clone is slower (but not really noticeably so
since the network traffic dominates).

In other words, I think you're making shit up. I don't think you
understand how little the SHA1 performance actually matters. It's
noticeable in benchmarks. It's not noticeable in any normal operation.

.. and yes, I've actually been running the patches locally since I
posted my first version (which apparently didn't go out to the list
because of list size limits) and now running the version in 'pu'.
