Right.  And you also can't assume that the context that passed
the brigade down the filter stack still exists by the time the
brigade reaches the last filter.  It's a safe assumption in
httpd-2.0, where the brigade is passed as a synchronous function
call, but it's not valid for apps in general (potentially including
future Apache versions) where the brigade may be queued up for
asynchronous processing by an I/O completion thread.
