bug#49439: grafts cause “guix environment” to get killed with OOM

Hi,

You could try something like:

  guix gc -D $(guix gc --references $(guix build pigx-scrnaseq)) \
    $(guix gc --references $(guix build pigx-scrnaseq --no-grafts))

Thinking about it, the grafts code depends on what’s in the store: when
nothing is in the store, it bounces to the “build handler”, which
accumulates the list of missing store items, until it starts building
them.

Let’s see if I can reproduce that behavior, too…

Thanks,
Ludo’.
