public class myservlet extends HttpServlet
implements SingleThreadModel
{

// service or doGet or doPost ... :-)
}

but from several emails in Servlet-List, if:
a there are several [copies of myservlet.class] have been
loaded by several ClassLoaders
b only one class, but there are several instances -- instance pool
c * myservlet.class has been loaded/unloaded several times.
* instance(s) has/have been made/un_made several times ?
* instance(s) has/have been reused several times ?
* [init] has been invoked several times
now I don't know if [SingleThreadModel] can [cross them :-)], I think
we need to try for different Servlet engine

and from several emails , perhaps we can try to put the
myservlet.class in [system classpath], so it will only be loaded
by [system CLassLoader?] or [Ext CLassLoader?] -- ? :-)
please [look] the emails of Gokul Singh and
Christopher K. St. John.

BTW, if we meet a problem, I guess perhaps the problem
of [SingleThreadModel]
is a little bit similar with the problem of [SingleTon] :-)
and I guess perhaps the problem is because that
Servlet is both a [server] and a [let] :-)
