Under normal circumstances you would have a fixed (or limited) thread pool,

Of course it does make sense to use pre-started threads.
How are requests queued if no threads are available in the pool ? If this is
done by a single (main) thread, this might introduce a bandwidth limitation.
Such things are usually configurable:
- Create new thread to handle the request
- Wait (as in: store in queue, and continue waiting for requests)
till a thread becomes available.
Just as a webserver does it.
In ExtPascal, it is impossible to separate the thread from the session.
This has the advantage of being simple, but doesn't scale, and creates
unneeded dependencies between different parts of the software.
It would be great to have an improved thingy similar to ExtPascal in the
Lazarus Library :)
It would, indeed. Darek Maszur has something similar to ExtPascal.
If you'd start with something like it, I think his implementation
would be easier to convert than ExtPascal.
