I had a real-world problem with avrgirl-arduino, which depends on this library, it turns out that, this library subscribes to receive data only after sending data to the board, on slower computers, this makes the board sends the response before the library starts listening to data, which makes the library lose the transmission and trigger a timeout error. The change passed on the unit test, and I've successfully uploaded the blink sketch to an Arduino Uno
