  Log Message:
  -----------
  Rename snek_pool_ref to snek_pool_addr

This makes the naming more consistent with the internal pool_addr
function and many of the uses where the return was called 'addr' of
some sort.

  Log Message:
  -----------
  snekde: Reset serial timeout under try block in case that fails

If the serial device has failed, resetting the timeout will
fail. Place that under the try block so that exceptions will be
ignored.

Also use 'with' statements for more locking so that exceptions will
cause the lock to be released, allowing the user to exit cleanly with
F4.
