If I recall correctly, the idea was that there would be a release of 1.33.1
30 September 2005. I will be leaving town this sunday 2 October. Do we
really want to mess with something that's been this way for a year and will
only go on for couple more days at this time? That doesn't seem wise to me.

Well, if we weren't doing that we wouldn't have a problem. So if its not
the same discussion but it is related. Of course we can test less. But the
root of the problem is that probably only a small percentage of the effort
invested in testing is actually testing anything. I know I've brought this
up before but made no headway so I won't harp on it anymore.
