Before the postpone filter you'll get subrequest bodies in your
filter, which is probably not what you want (the postpone filter
is to glue subrequest together, correctly ordered).

The HTTP_AUX_FILTER_MODULES is a generic queue, and it's the
only one currently officially supported for 3rd party modules.

If you want your filter to be called right before/after postpone
filter, it should be relatively safe to put it into the
HTTP_POSTPONE_FILTER_MODULE variable though (and may be with some
additional checks to make sure the postpone filter is enabled, or
just a code to enable it unconditionally).
