My understanding of this is close but not quite the same.
The "wait 0 with messages" statement is the fastest implementation 
("wait 0") of an opportunity for the system event loop to process any 
pending instructions. The "with messages" statement in effect yields 
control to the event loop to check if any "send in time" messages have 
timed out and are pending or to handle other tasks that may have 
accumulated (mouse or keyboard events, etc).
