That does seem right, and as Stas noted, APR.xs does that
already. But when I tried the apreq stuff from within a CGI
environment just by using APR and APR::Pool, things crashed,
which was cured by putting in the apr_initialize() call from
Apreq::Base (I'm not sure if this problem is at all related
to the disabling of some of the mp2 apr-ext/ tests?). I'll
look at this in more detail, though - you're right that in
principle an Apreq::Base like this shouldn't be needed, or
even done.

In any event, I did this more as a proof of concept, in that
it shows things seem workable in principle within a cgi
environment, and even from within the current state of mp2
where must be used (as an so providing some
symbols). Is the perl glue something that you think should
be persued to more detail now, or should we wait until the
necessary symbols needed from are moved
