Oh, that's less bad than I expected. The discussion in the other thread
was pointing in the direction of needing hundreds of ms to make indexes
that are big enough to hit all the code paths.

Yeah, I was imagining teaching 027_stream_regress.pl to run additional
scripts that aren't in the core tests. (I'm still quite unhappy that
027_stream_regress.pl uses the core tests at all, really, as they were
never particularly designed to cover what it cares about. The whole
thing is extremely inefficient and it's no surprise that its coverage
is scattershot.)
