Btw, have you had a chance to run the above to scan your repos?

The 19GB RSS would interact poorly with more frequent fork+exec;
such as the change to do unconditional expiry of long-lived
cat-file --batch* processes:

If you run Inline::C + PERL_INLINE_DIRECTORY to use vfork
instead of fork, then RSS won't affect process spawning
speeds.

But yeah, 19GB RSS still sucks and I'd like to get to the bottom
of it.
