Kevin,

With Revolution you don't have to worry about garbage
collection ; temporary variables are released at the
end of the handler in which you use them,
script-locals and global variables stay until you
'delete' them or quit.

Revolution doesn't have a multi-threading architecture
in the traditional sense : you can 'send <message> to
<object> in <time>' and those messages are then
scheduled into a queue and handled at idle time as
soon as possible after their trigger time.

Some commands (the socket commands in particular) can
be used with a 'callback' parameter, allowing your
application to handle other events while you're
waiting for the command to complete ; once completed,
the engine will call your callback handler so you can
act consequently.

For more information regarding 'send', I recommend Dar
Scott's excellent primer on message mechanics, which
you can find at the following location :

Hope this helped,

Jan Schenkel.
