This seems to be the problem. I was very surprised when I found that
using "tla changes --link" actually made tree-lint and changes *slower*
rather than faster.

Do you have a version of your relink script that can actually *unlink*
all of the files? :)

No, and I'm deeply offended by the suggestion :-)

Okay, I suspect it wouldn't be that hard to do. Mainly, you need to write a variant of walk_candidates that outputs only things that *don't* need to be hard-linked.

Then, instead of re-linking, copy the file to a tempfile, make damn sure you set the permissions properly, and rename it over top of the original.
