Yeah that's exactly it, there's a separate application running that is delivering COM objects to my python script. Each object is its own callback which requires a Dispatch call to get access to the properties. This can be several thousand in a very short period of time and while this happens my other thread will attempt to create a COM object and seems to hang on the Dispatch call. During very high loads, the 2nd thread that is trying to create a new object can hang for almost a minute.
