I know this can wait until the next development cycle, but
just to record this ... For some reason just using APR.pm to
call apr_initialize/apr_terminate (through APR.xs) doesn't
seem to work for the CGI environment, and yet putting the
same code in an Apreq/Base.xs:
================================================================
BOOT:
     apr_initialize();

void
END()

   CODE:
   apr_terminate2();
================================================================
does work. I'll look into this some more ...

If you copy this from APR.xs, make sure to copy the whole BOOT. apr_initialize 
has a bug in its init, which is worked around in APR.xs.
