I wrote a naïve patch to use Judy for ruby's internal tables in 2002; unlike
yours, it replaced all st_tables IIRC, but some of the feedback from Judy's
author might still apply, see [48365].

matz took a look at Judy last year, see
http://www.rubyist.net/~matz/200...
He seemed pretty excited about it, but the license (LGPL) would make
integration a bit cumbersome.

Normally, a patch like this should be tested in HEAD before it gets in the 1.8
branch, but it's knu's call, of course.

PS. please don't include all of configure when just configure.in will do ;)
