Your assessment is correct: a 'send' will not execute
until the end of the current thread of code.
The idea is: 'Send' actually puts it on a to-do list,
which it will go through once the normal exectuion of
the handlers has ended.
Then it will see if there are any 'pendingMessages',
and check if it is time they are executed or not.
So in your example, cmd2 and cmd3 will be executed
_before_ the sent message is handled.
Hope this cleared things up a bit,
