In the discussion on "select bug", some people noted that select does not 
wake up a process until the buffer is half full (or all full, or
whatever). Does this mean that if a small amount is written to the
device/pipe the process may never be woken? Or is there a time limit that
wakes up the process after a certain amount of time if there are _any_
bytes in the pipe/dev?
