How is SingleThread model implemented?

[javalatte]

If your servlet implements the SingleThreadModel interface, then your servlet instance doesn't process more than a request at a time. Now how does the server implement this model and handles the request, sequentially or parallely?

As a programmer I don't know the behaviour. Depends on vendor (server provider) implementation.

Might be,
- process request sequentially
- enable parallel execution by having servlets object pool

but We don't know exact behaviour and it can change server to server.
