Actually, with sync MFTs, ::ProcessOutput is blocking until a sample is 
yielded or an error occurs.  In MFT writing guides from Microsoft I've 
seen, ::ProcessInput just buts the data in a buffer, and ::ProcessOutput 
actually invokes the functionality of the transform.  This should match 
that behavior pretty closely.
