Running many scripts at once

Scripts under hat blocks usually run to completion when that script is triggered, before the screen is updated. The exceptions are:

• when an ‘and wait’ call is made, e.g., broadcast_and_wait();

• during a while or for loop: one iteration of the loop runs per display frame.

TODO: Other syscalls also suspend for a frame; check and document this.

One consequence of this is that if you have a very complex piece of processing inside an event handler, your project might appear to have crashed. Try to keep things simple!

(The information above about while and for loops is slightly simplified. See the Threading Model help if you would like to know the full details, although most Pytch programs will not have to worry about this.)
