Why Nginx Doesn't Implement FastCGI Multiplexing?

[momyc]

Well, there is supposed to be one FCGI_REQUEST_COMPLETE set in reply to
FCGI_ABORT_REQUEST but it can be ignored in this particular case.

I can see Nginx drops connections before receiving final
FCGI_REQUEST_COMPLETE at the end of normal request processing in some cases.
And that's something about running out of file descriptors.
