I tried it on my Mac M4 laptop, and saw the 002 test dropping from
3592 ms to 540 ms, about an 85% savings.  So I agree this is worth
doing.  It's still unclear why Robert is seeing times so much worse
than mine, though.

I didn't read the patch too carefully, but the changes in the
002_inline.pl script itself seem reasonable enough.
