Thanks for the debug info. Sorry for not asking this earlier, but can
you also give me the output of `pstat -t` for cuau0?

It's a bit strange the read() on the TTY returns EAGAIN, since this
doesn't seem to be generated by the TTY layer itself. It also seems
moused is pretty badly written, looking at how it operates on fd_sets.
