492027fa7a Fixed a bug in bit field instruction decode 
We were trying to decode the effective address before fetching the
second instruction word for bitfield instructions, which was causing
it to use the wrong word for the offset:width information, which was
preventing the shell from printing to the screen after boot

93c9307829 Moved I/O to a separate thread 
but I'm not happy with it, and will likely change it in future,
possibly to use two threads and two sets of channels to pass chars
back and forth
