I recall that Apache offers a choice of worker processes or worker 
threads. I suspect mod_php is not thread-safe, so you have to use multiple 
worker processes. And process creation on VMS is expensive.

I wonder how Nginx deals with this: I don’t think it can load the Apache-
specific mod_php, so it offloads PHP to a separate process and uses 
“reverse proxying” (actually server-side proxying) instead.

Server-side proxying is the way to go, anyway: I use it for my Python code 
now. It lets you manage your own process context, create your own 
subprocesses/threads/tasks ... whatever you want.

And I can use WebSockets as well, which PHP has trouble supporting.
