i think that the queue (bucket?) also has a limit on the number of requests
that it will hold and if this is reached, then in FIFO fashion, the first
in is dumped since it is also the oldest...
Do I understand correctly that Apache performs the queuing ?
Apache performs it's own queuing, independent of FastCGI, CGI or whatever.
So The FCGI interface would need to provide it with additional information
(e.g. if any or how many threads are still available) _before_ it opens a
connection to the FCGI "Server" (as this would go directly to the thread and
not to some kind of thread-scheduler).
No. You probably misunderstood what Waldo wanted to say.
What he said pertains to the inner workings of Apache, and is independent of
how a particular request is handled. It pertains to how Apache handles new
connections on its HTTP socket. No more, no less.
