What devices does select apply?  I know select() is designed to be used with
serial and event devices, but does it apply to pipes or ordinary files?  
Under SCO Xenix V/386 R2.3.2 select() *always* indicates data is available
from a pipe, including empty pipes.  Is there a standard for select()'s 
behavior on pipes?
