That would help remove the perception of a suggestion towards
threading. But what I was really looking for was something to help me
choose whether or not to use threads at all. I couldn't find this clear
answer in the perl documentation. Geoff suggested that if stability was a
priority and performance was not, particularly, then I might as well stay
away from threads both in apache and in perl. Later I found a tip for
installing apache2 for FreeBSD (in the apache docs) that warned against
using threads on FreeBSD in any event. So I made what seems now to be an
obvious decision to not use 'em.
But I think it would be better if the pointer you _do_ have in the docs,
which I quoted, saying that threqads should be avoided unless there's a
really good reason why not, could be emphasized or clarified more.
