[Lazarus] library initialization finalization syntax

[Bernd Kreuss]

the problem is, that a normal thread does not have a message queue.
You can create a second thread, which calls some method in a periodic
cycle and sleeps in between. But you must take care, that this thread is
synchronized to your daemon thread.
