[plt-scheme] Noticeable slowdown after 369.4

Attached is a program of mine that is notably slower with 369.4 than
it was with 301.4 -- and I'm pretty sure it's also slower than it
would have been just a few days ago, before the precise GC became the
default (I'd be happy to check if you want).

To run the program, just type "make check" -- assuming that you've got
an English dictionary in /usr/share/dict/words.

On my machine, it took 40 seconds under 301.4, but now takes about
twice that.
