What is the value in /proc/sys/vm/overcommit_ratio?  I think the default is 50, so you could up it to 100…but I mean, the underlying problem is that you're using 2 in overcommit_memory.  It seems that this setting is made to ignore MAP_NORESERVE by design in that it *always* checks to see if you have enough physical memory + swap as determined by your overcommit_ratio.  I think it's pretty unlikely that JSC will actually use that much memory.  If it does, then that is very likely to be a bug :-)  In the end though, if using 0 or 1 is a deal breaker…

tldr; (you|we)'ll have to go with option #2 from comment #1.
