[OLE #98] Re: By-pass RPC Runtime If Possible When Calling An STA

After the change [2] running ole32 marshal test makes the process 
unkillable on my winME.  If I change the code, things get running OK:

|  static DWORD CALLBACK no_couninitialize_client_proc(LPVOID p)
|  {
|      struct ncu_params *ncu_params = (struct ncu_params *)p;
|      HRESULT hr;
|      IUnknown *pProxy = NULL;
|  
|      pCoInitializeEx(NULL, COINIT_APARTMENTTHREADED);
|  
|      hr = CoUnmarshalInterface(ncu_params->stream, &IID_IClassFactory, (void **)&pProxy);
|      ok_ole_success(hr, CoUnmarshalInterface);
|  
|      ok_more_than_one_lock();
|  
|      /* die without calling CoUninitialize */
| +    CoUninitialize();
|  
|      return 0;
|  }
|  
|  /* tests STA -> STA call during DLL_THREAD_DETACH doesn't deadlock */

It seems call deadlocks only on my machine.  Rob, can you tell me, please, 
how can I find out, is there some problem with my box setup or is this a 
bug in test-code?
