I am running git annex uninit on a quite heavy in number of annexed (text) files repository (can share a tarball if needed -- the product of https://github.com/con/tinuous/ to please those hating CI log navigation UIs ).

the box on which it runs is very IO busy ATM, but the fact that I saw no progress from uninit for almost 10 minutes made me look into:

so git annex invokes separate git rm on each file. Having thousands of those is doomed to make it slow. Unfortunately I have not spotted a --batch mode in git rm --help but I wondered if may be at least multiple files could be requested to be removed in a single call instead of running that rm per each file?
