equery uses 2 GB of memory without crash on machine with 8 GB memory

In a recent optimisation I'm looking to merge at https://github.com/gentoo/gentoolkit/pull/2 , memory usage also decreased significantly (probably because it loads a lot less of Atom instances in memory). On my machine with gentoolkit 0.4.2, "equery d -a llvm" consumes up to 1.1G (time -f "%M") of memory, and with that patch above, 120M for the same query. I'd say that this patch would fix the bug...
PR has been merged long ago, but I am getting a new error with current portage
