Ok, I've updated to the latest changes in the 3.5 branch of the
qtruby/korundum and ran my program through valgrind for about 24 hours to
accumulate where the leaks are still coming from.  Here are the two big
offenders:


==15683== 15,177,794 (897,708 direct, 14,280,086 indirect) bytes in 
224,427 blocks are definitely lost in loss record 391 of 391

I can definitely see HOW the memory is being leaked, but it's not entirely
clear where the responsibility lies for cleaning up the heap objects after
they are created.  I may just stab at it for a while unless you have any
thoughts, Richard?
