D'uh. y'know, I think I changed that first and then realized I didn't need
to but forgot to back out :)

Yep, nice.

See other message. Forking gives you back some responsiveness.
[snipped suggesting for measuring space used]
Good god, man, without persistence I'd have to *reindex*. No way ;)

That seems high, after niling all those things and gcing:
memory 32,311,120 bytes
old 28,114,280 bytes (87.0%)
young 124,272 bytes (0.4%)
used 28,238,552 bytes (87.4%)
free 4,072,568 bytes (12.6%)
(Closed some extra stuff too.)
Well, that's my starting point. I'm going to index the whole thingy and
see how it goes ;)
Cheers,
