Both of these patches seem to improve matters quite a bit.  I haven't yet
thought too deeply about it all, but upon a skim, your patches seem
entirely reasonable to me.

However, while this makes the test numbers for >= v16 look more like those
for v15, we're also seeing a big jump from v13 to v14.  This bisects pretty
cleanly to commit d872510.  I haven't figured out _why_ this commit is
impacting this particular test, but I figured I'd at least update the
thread with what we know so far.
