I don't like this. On Windows, rebase -i is already slow, and these extra
processes will make it even slower.

This is 'rebase -p' case, and you trade the new processes for some old ones.

But in the regulare case, you don't; the processes are really new.

Anything that can be done about this? Perhaps the rev-list call can
generate all of the full SHA1, the short SHA1, and the subject with a
--pretty format?
