Spent ages tracking down a memory leak in the assistant that showed up when a lot of files were added. Turned out to be a standard haskell laziness induced problem, fixed by adding strictness annotations. Actually there were several of them, that leaked at different rates. Eventually, I seem to have gotten them all fixed:

Before: ?leakbefore.png After: ?leakafter.png

Also fixed a bug in git annex add when the disk was completely full. In that situation, it could sometimes move the file from the work tree to .git/annex/objects and fail to put the symlink in place.
