Can't we just gc the pure space too?
At least with the mark-stack functionality, that would be fairly trivial.
BTW, wouldn't it be about time to drop the old GCPRO stuff -- IMHO it
is just too time-consuming to maintain (and it is practically
impossible to find those bugs).
What platforms cannot use mark-stack? Are they really worth
supporting?
[after all, emacs 21.4 _is_ still available on those platforms, so
users on those systems are not completely lost].
