Yeah, no worries--you guys are busy enough as it is. As far as adding
it to the commitfest goes, I did, actually. Should I add the comment
with the testcase as well? I'm investigating further and it's looking
to me like what I'm really up against is O(n^2) behavior in the
optimizer for OR clauses, but I'll keep looking--don't want to say
anything too prematurely.

Also read that--did I do something wrong? I tried to make sure I
followed its guidelines. Anyway, thanks for the response :)
