Hi!

Oh, that’s an RSS of 6 GiB for ‘guix pull’ itself?  Weird, I don’t see
how that can happen.

Could it be that ~/.cache/guix/checkouts/THE-THING is too big, which in
turn causes libgit2 to consume too much memory somehow?

What happens if you attach strace to this process at the moment where
it’s consuming a lot of memory?  Is it traversing Git pack files or
something like that?

TIA,
Ludo’.
