FastCGI doesn't imply PHP (and, actually, PHP doesn't imply
blocking as well - there are some event-driven PHP frameworks out
As of now, implementation of the FastCGI protocol in PHP doesn't
support FastCGI multiplexing at all, and that's one of the reasons
why nginx doesn't implement FastCGI multiplexing as well. Quoting
