If Catalyst::Engine doesn't cleanup the body of the request, it
doesn't really sound like C::P::JSONRPC to me.

I'm also curious to these. If there's a better way to fix this inside
C::P::JSONRPC, I'd love to apply the patch.

Do you experience the same issue with the sandalone server or
mod_perl? If not, it definitely sounds like Catalyst::Engine's FCGI
