Also tested that 4M was not large enough. Sean is also testing 45 * 1024 * 1024 on 32-bit arm* buildds. Though 4.5M is probably sufficient for now, I wonder whether it's acceptable to further increase this to 5000000 to be more future proof? On the other hand, I see there are threads on emacs-devel talking about removing pure space. Is that referring to this pure lisp storage?
