#startUp is not supposed to start the server. #startUp is the message
sent to notify of image startup. You can implement it to do
initialization if needed (take a look at WAListenerAdaptor in the
command adaptor package, for example, which uses it to reinitialize a
Proces, *but only if the adaptor was running when the image was
saved*).

Many adaptors do not need to implement #startUp, but if you do, you
should not start up unless you were running on image save.
