Why Nginx Doesn't Implement FastCGI Multiplexing?

[momyc]

If it's time to close backend connection in non-multiplexed configuration
just send FCGI_ABORT_REQUEST for that particular request, and start dropping
records for that request received from the backend.

Please shoot me any other questions about problems with implementing that
feature.
