I tested your patch and it works like a charm! Tested it a number of 
times, based on the number of bytes received, only the hashes and 
modified blocks where transferred. Also did a sha256sum on both devices 
after every attempt, just to be sure, and they matched every time.

One very minor visual glitch is that the %process is still stuck at 
-2147483648% (I guess min signed int) during the transfer. But this is 
just a visual thing, doesn't impact the transfer.

I agree, thanks Wayne for your quick response!
