void dontwait ()

Tell the uithread component not to wait for the threads to end

Normally, uithread waits until all threads have ended. Any thread may call dontwait() to change this behavior. This is generally used by a dialog poping a non modal sub-dialog. The uithread component is used to pass information (using glocal variables) to the threads. The threads grab a copy of the information and tell the component to end.
