o If we come out of select() with only write descriptors that
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.
