hi Robby Just back from out of town, sorry for the late reply. No. This doesn't help at all, still got low-memory killing on my ipad. Actually, my own test is all based on "#lang racket/base". I'll try Kevin's patch to see any difference. I've also tried to throttle the max_pages_in_heap to allow around 25MB pages to use, it will soon throw "out of memory" exception and abort after a couple of GC cycles.
