ContextSwitchDeadlock was detected

There is a bug in .NET RCW when frequently calling COM and/or COM+ components that use STA threading model.  The fix is to use the code from here.   In order to avoid the following error:

ContextSwitchDeadlock was detected

Message: The CLR has been unable to transition from COM context 0x16daf0 to COM context 0x16d8c8 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.
