The waits will nest.

You should use an event style of programming; the multi-threading style 
will not work.

You can poll with a send-in-time cycle.  Or you can use a setProp or 
other changing function, to send a message upon a change of some 
parameters or variables.

The Primer on Message Mechanics might give you some ideas, too.  Find 
it here:

The basic idea of the event style is that each event (user action or 
I/O event or delayed message created with send) makes a change to the 
state of your program perhaps such that other user action or I/O events 
or delayed messages are destined to come, all creating the behavior you 
want.
