Thanks for replying to my pull request (although indirectly). Yeah, I
don't like the name of that directive as well. I chose that just
because I can't find a better name at that moment :P

I just copied (almost) the way that ngx_http_upstream does buffered
outputing ;) To be honest, I didn't and don't see how that allocation
can be totally avoided for general use cases. Silly me! :P

It'll be great if you provide some more elaborate suggestions or even
patches to my patches if you do have the tuits :)

Just as Piotr mentioned ealier, the initial motivation for my ngx_eval
branch is to provide support for ngx_drizzle + ngx_rds_json. Adding
subrequest-in-memory support to every content handler/upstream handler
*with* output filter support is boring and no fun. So I chose to fix
ngx_eval rather than my content handler/upstream modules ;)

Thanks!
