Not quite. I recognized some problems in GIT that could cause issues, so I wrote "babysitting" software that constantly combs through the GIT tree, making sure that all submodule references are up to date with the latest code and similar housekeeping tasks. That babysitting software can and does trigger commits to the tree, and it is these fixup commits that are taking a long time to carry out.
Looks like that needs a bit of optimization. I can have a look at it and see if there's a faster way to do the same thing, if you like. (And if the code is publically visible.)
