On the AOLserver list, there've been comments off and on for ages
(principally by non-OpenACS users, I think) about how it would be
preferable for the OpenACS request processor to play nicer with other
AOLserver filters, rather than insisting on always running first, and
then hijacking all processing of the request from then on. I don't
recall the details, but that sounds related to what you're talking
about, Dave?
