As i said on that bug report, there's no way for us to allocate memory without actually having it reserved/written by the OS. So that 'fix' won't apply (at least on OpenBSD, dunno for the others). We have a low ulimit -m to 512Mb by default on purpose, so maybe only OpenBSD is affected by that problem because of that 1Gb allocation.
