Prozess bei laufenden Thread beenden

[Der schöne Günther]

Zitat:

When you exit a VCL application, the background threads are just killed off. The application does not wait for them, it just ends. If you want to wait for them, you will have to write the code yourself.

A VCL application, however, will wait (for all eternity, if necessary) for all the tasks that were put in the default thread pool (System.Threading.TThreadPool.Default).
