So here we make this static file-level etc...

...but all of the "tmp_objdir" usage is in one function, can't the variable be declared here instead?

We need to hand the "remerge_objdir_location" off to the "rev_info" struct, but that seems separate from its lifetime.

Re my [1] & [2] I like Neeraj's "atexit cleanup" approach better, perhaps that makes your cleanup in log-tree.c redundant or easier?

Per [2] it looks like you need to "hand off" the "remerge_objdir_location", so having the struct live in tmp-objdir.h as I suggested in [2] might make that work...
