So there are a number of things that could be messing up.

1 - I believe that the Arduino has an FTDI USB to serial chip
on-board, which can apparently buffer characters and not deliver them
when you think you should get them.

2 - I don't know if the Arduino has a FIFO on it's UART. If not, then
you'll need to read the characters quickly (with no prints between
characters) otherwise the characters coming from the gumstix will
overrun the UART.
