> Event can be lost if produced while a response is being prepared. I've at=
tached an example where a push event is used to refresh a count whenever an=
event is fired. It's using Thread.sleep to simulate an event being produce=
d while the response is being prepared. Note, if the sleep just before retu=
rning the count is removed it all works fine, and the page is refreshed eve=
ry 5 seconds, but with the sleep in place the event is lost.
