Oh - I should have pointed out that for benefit of users attempting to
build httpd after it's release next week, I'd really like to promote
the "preferred" patch.  So please chime in which patch we should be
promoting.

A quick look at BSD shows no support.  Linux and Solaris both seem to
support GROUP_FILTER_SIZE - so my preference is for the 'cleaner' patch.
