Tim did mention this as a bug on March 14.  There wasn't any mention of
whether it was a serious enough problem to try to fix in 3.5, so I ignored it
for the moment, hoping that someone would come up with a fix.

It did appear to be possibly related to the ClassBuilder problem, but that
wasn't certain, either.  The problem occured with or without the ClassBuilder

Just now I did a quick check of when the bug was introduced.  I was guessing
that maybe Andreas introduced it with the ClassBuilder refactoring/cleanup in
3.4alpha, which was when the other ClassBuilder bug was introduced.  However,
that was not the case... I tested 3.2 and the bug is there, too.  Turns out
this bug is as old as the hills... the bug exists back in 2.6!  It does not
exist in 2.4, though.  (It's always nice to have old images lying around. :-) 
I didn't have a 2.5 image handy, though.)

So, given that the bug is 3+ years old, and we don't yet have a fix that we
agree on, I think it's pretty safe to say that we don't need to address this
in 3.5.  As soon as someone comes up with a good fix, we can include it in
3.6alpha.  (Maybe Brent's fix is sufficient, I don't know, but it hasn't
gotten any feedback yet.)
