Apache and isapi

Correct me if I'm wrong but this is what I think I read.

When Apache receives a http request for a cgi program it starts a new
process for each request.

With IIS using isapi, the isapi dll resides in memory and its entry point is
called with each http request.

1) Does each isapi request start a new thread?
2) In Apache you can use mod_isapi but does this work the same way?
3) Otherwise how does Apache handle multithreading and worker pools (or
equivalent)?

For others wondering the same thing:

ISAPI is an API that you can use to extend Microsoft IIS, SIMILARLY TO HOW
YOU WOULD USE THE APACHE API.

Now all I've got to do is fight to find "good" docs on the API.
