Awesome, I got it fully working using this method. I gave up my battle against the subrequests and switched over to creating new requests in the same manner as your supervisord module. There's a bit more trickiness needed, since these new requests will need some of the pieces of the original request (some of the original request's configuration, headers and server variables in my case).

I don't have the headers working completely correctly yet, but everything else seems to work perfectly.

I might be able to package this up as a generic subrequest replacement. At the very least, I'll clean up the code and post it somewhere for everyone's perusal.

Thanks a bunch to both of you (Piotr and Agentzh) for your help.
