BUG: Multithreaded applications can deadlock because of asynchronous cleanup

Under certain conditions, a class that is derived from the System.EnterpriseServices.ServicedComponent class that runs in a COM+ application may stop responding (deadlock).
This problem is caused by an Activity deadlock. Activities can deadlock on multithreaded applications because of an asynchronous cleanup of component references.
To resolve this problem, the client of the COM+ objects should systematically call the Dispose method. This call enables deterministic cleanup of the COM+ objects. You must call the Dispose method when you have finished using ServicedComponent objects.
Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the "Applies to" section.
