One question is whether there should be BEGIN_DEPLOY/END_DEPLOY
notifications that would allow one to determine the outcome of the
deploy.
That means we would need:
BEGIN_DEPLOY/END_DEPLOY
BEGIN_REDEPLOY/END_REDEPLOY
BEGIN_UNDEPLOY/END_UNDEPLOY
to be able to know the result of the action, wouldn't we?
In fact to prevent the 404 I just need to forward the BEGIN_REDEPLOY to
Apache httpd. (Tomcat has its event to tell that a Context is up again).

Most likely a begin/end notification is the cleanest way to
introduce
the notifications.
