// If this thread has not called CoInitialize yet, but some other thread

// in the process has called CoInitialize with the COINIT_MULTITHREADED,
|
|
// then that infects our thread with the multithreaded virus, and a
|
|
// COINIT_APARTMENTTHREADED will fail.
|

|
|
// In this case, we must turn around and re-init ourselves as
|
|
// COINIT_MULTITHREADED to increment the COM refcount on our thread.

// If we didn't do that, and that other thread decided to do a
|
|
// CoUninitialize, that >secretly< uninitializes COM on our own thread
|

// and we fall over and die.
