Hi Len,

The SingleThreadModel Interface is _not_ used in the servlet.

Maybe I should write a bugreport?

Thanks for your help!

I don't see anything there that would cause the servlet in mydomain2
to be loaded 4 times. The only thing I can think of is that the
servlet might be running in single-thread mode (by implementing the
SingleThreadModel interface).
