Actually, there's a very serious inefficiency in many uucps.  Because
packets are being received in raw mode, the receiving process can be
awakened on every *byte*, do a 1 or 2 byte read, then try to read some
more.  This sort of behavior can eat a machine alive!  There have been
several attempts to fix this (and System V uucps don't have the problem),
but not all of them work well.
