The flash SLOG system took around 12 hours to complete freebsd-update

freebsd-update and a very pathological 'install' command performance.
I spoke with mjg about this and because my pools do not have block
cloning enabled, copy_file_range turns into a massive pessimization in
'install'.
I reported on IRC what I think is the same issue, except in my case this
was on an MMC and took many days (I stopped paying attention after 3
days).
