Probably a good idea, assuming the core size increase is natural and
doesn't reflect some deeper problem.

Aside: why do we even bother with the malloc-on-pure-overflow logic? We
can't GC once we've overflown pure storage (although that could be made
to work), so an Emacs in that condition isn't very useful. Wouldn't it
be simpler just to abort when we overflow pure storage?
