Perhaps setrlimit would be the most reliable overall.

I struck a bug lately in 1.8 where the collected cell counts are somehow
botched, leading to it wrongly thinking new heap is needed again and
again.

It's not supposed to.  The rule is supposed to be to increase the heap
to make 40% of it free, after gc figures what's free and what's not, or
something like that.  In practice it means blocks each 1.6x (or so)
bigger than the one before getting allocated.  (As seen in `gc-stats'.)
