select takes descriptors 0 to 2 as a console title's terminal with no input: 0 is never readable and 1 and 2 are always writable. poll threw for them unless the host happened to attach a pipe, so the same title could select on its standard streams but not poll them. poll now gives the same answer, with POLLOUT, the one bit ttydev_poll reports for a writable terminal, for 1 and 2 and nothing for 0.
