end up writing zero bytes, sleep for 1/10 of a second so that we don't end up using up too much cpu. This should only ever happen on systems that wrongly report a descriptor as writable despite the tty buffer being full. Discussed with: Jeff Evarts o Do an initial run-time check to see if select() alters the passed timeval. This knowledge isn't yet used, but will be soon.
