LGTM, good to be merged in once CI is clear

@rbharath So the CI is crashing I think because of the high memory of the tests. They pass on my machine. I have lowered the memory requirements of the tests so they don't crash, but I promise this PR won't blow up the CI if you need to merge it tonight before the CI finishes.

Edit: It's clear to merge
