After applying the 'giflib' and 'curl' updates to the 'dbus-update'
branch (and also merging master), the number of queued jobs on that
jobset went from about 1000 to over 2200.  Based on this, and also based
on my past memories of curl security updates, I suspect that this is
another case where "guix refresh -l" drastically underestimated the
number of rebuilds.
