Renaming the directory isn't necessary. The packs won't be used until they have a .idx file. That .idx-file is written after the packfile, so any operations on the repo will simply use the old, loose, objects before the packing is completed.

The worst thing that can happen is that an object about to be fetched is deleted in its loose version before the upload-pack program can open it, but that's no worse than having the entire directory being moved out from under it.

On a side-note, this is a grade A example of something that should typically be done sunday night at 4am.
