Was this from /all/ (ALL.git using batch-file) or Gcf2?

The old stuff has timers to do periodic cleanup, but the new
stuff is trickier as the cost of a restart is higher...

It should be alright to wire up the old timers to ALL.git with
(hundreds) of inboxes lore currently has.  git 2.33+ should be
better when we get into the thousands; but it's still not

Gcf2/libgit2 startup time is slow compared to git 2.33+, but
I can write a dumb fstat loop to periodically look for

At some point, I'd like to fix git.git to release packs
(and add alternates dynamically)
