As far as I know, all system messages are always sent to the current 
card, including startup, on every OS. It's pretty common to place 
handlers in the card script of the first card if you only want them to 
run on startup.

Startup should be passed from the card to the stack normally on any 
platform as long as you don't have a blocking handler in the card that 
stops it. I think the docs are misleading about where the message is sent.

That said, I've seen some anomalies lately with the message path that I 
can't quite pin down or get a recipe for.
