That depends on entirely on Boehm GC. 

Btw, the documentation on WaitForPendingFinalizers says "...there is no
guarantee that this method will terminate...", thought they propose
interrupting the thread that called WaitFormPendingFinalizers as an

In the AppDomain.Unload documentation they say, for example, "Althought
