No! If threads were generated "behind your back", you'd have a very
hard time handling the resulting mess.

The Recipe is about the other, harder half of the problem -- a
thread different from the GUI-controlling one wants to talk
with the GUI-thread. Starting a new thread from the GUI one
(e.g. from a callback: all callbacks run on the GUI thread!)
is easy, with module threading; the problem is coordinating
multiple threads, and the recipe helps with that part.
