You can have as many threads doing stuff as you want, however, they must all
serialize their DOM updates through the UpdateManager's queue. The
UpdateManager has a single thread that actually performs the DOM updates.
Your threads are not allowed to manipulate the DOM directly (otherwise,
there would be a race condition).
Basically, everywhere you would want to do "manipulateDOM()" you instead
must do:
canvas.getUpdateManager().getUpdateRunnableQueue().invokeLater(
new Runnable() {
public void run() { manipulateDOM(); }
});
This is similar to the rule for programming in Swing, where updates must be
done in the Swing thread.
