IIRC, the situation was that unexec builds were broken on master at the
point I proposed the pure space removal.  I filed a bug about unexec and
things were fixed some time later.

Pure space and unexec aren't closely related at all, and the rebased
scratch/no-purespace branch, after some tedious fixes, starts fine when
configured with --with-dumping=unexec.

What do you think about making pure space overflow fatal as a first
step?
