Thomas says no for 6.1p1.  I have no opinion on this.  However, I don't
want to rush out a fix until I have heard from Paul M. Aoki and Vadim,

I think the sort is used by ORDER BY and joins where this is not an
existing index.

I am not sure how to do this.  There is sysctl() and getconf(), but
neither of them is standard on all platforms.
