Comment (by bgamari):

 Thanks for picking this up, duog!

 I was in the middle of writing a reply starting with,
 > The issue with this approach is that we will now have runtime which
 won't be accounted for. The heap census can be a considerable amount of
 time...
 when I noticed that we already have a separate set of fields for
 accounting heap census time. Presumably this means that we were double-
 counting time previously. Anyways, this suggests to me at least that your
 approach should be fine.
