I think the 'By default' applies to the SingleThreadModel case - it's the
"there must be..." that is more relevant.
In fact in section 3.3.3.1 the spec says
"However, the container must not create an instance pool as it does for
servlets that implement the SingleThreadModel. It is strongly recommended
that developers not synchronize the service method or any of the HttpServlet
service methods such as doGet, doPost, etc."
Pretty conclusive I'd say!

No, the statement starts with "By default.." wich means it recommends
an behaviour wich can be configurable/overriden.
