That's already been addressed; we just test for lots fewer things now,
and thereby do fewer loops. That's the only issue with slowness that's
appeared until now; nobody's complained since those changes were made.
I've tried converting the entire script to use C++ by default (since
that's the environment under which all this will operate anyhow), but got
lots of weird failures in otherwise-good tests. And again, the part that
causes slowdowns is where we're testing for correctness during C linkage.
We have to change to C for that.
