This sums it up pretty much, yes. Using threads means your program
flow is now asynchronous, which in turn means that you cannot rely
upon a specific order of thread execution (see
http://en.wikipedia.org/wiki/Scheduling_(computing) for some basic
information). What you can do, however, is provide QWaitConditions or
other locking mechanisms to ensure that one thread will wait for
another, if needed.
