I was up at the crack of dawn wrestling 100 pound batteries around for 3 hours and rewiring most of my battery bank, so today is a partial day... but a day with power, which is always nice.

Did some design work on finally making transfers of files from direct mode repositories safe, even if a file is modified as it's being uploaded. This seems easily doable for special remotes; git to git repository transfers are harder, but I think I see how to do it without breaking backwards compatability.

(An unresolved problem is that a temp file would be left behind when a transfer failed due to a file being changed. What would really be nice to do is to use that temp file as the rsync basis when transferring the new version of a file. Although this really goes beyond direct mode, and into deltas territory.)

Made fsck work better in direct mode repositories. While it's expected for files to change at any time in direct mode, and so fsck cannot complain every time there's a checksum mismatch, it is possible for it to detect when a file does not seem to have changed, then check its checksum, and so detect disk corruption or other data problems.

Also dealt with several bug reports. One really weird one involves git cat-file failing due to some kind of gpg signed data in the git-annex branch. I don't understand that at all yet.
