It said on the web site to throw ones patches this direction.

Here's one for a bug submitted [and fixed] about 6 months ago.  Guess
I forgot to submit the patch itself.
This is a fix for the following leaks:

def leak
 "name".split(/::/)
end

loop {leak} # leaks

def grow
 for i in 1..100
   eval "b#{i}
 end
end
1500000.times {grow} # leaks
[this style of leak is reported on several web sites as a ruby leak, as well]

Reservations:
I just added this patch from someone else's post--I'm not positive
there aren't side-effects, though I haven't seen any.  I'm not scope
pro here :)
Also for some reason this worked on my Linux machine but not my mac
machine [still leaks].  Maybe because of my linking to some old
'legacy' libs or something.
Let me know what I can do to help it get accepted.
