That's why I used the example of a build under the chroot, because the compiler is not a small program. Consider when the memory *is* used, and N * 2GB implies lots of paging, where the previous N * 32MB did not. I'm saying that we should consider a setting more like 128MB or so, since the value cannot be changed from the command-line, or through the environment. r~
