  For what it might be worth, this little page shows the kind of thing you
  have to do in the usual Unix system calls framework.

  I do not think this should comfort anyone.

  There are a number of useful things in the C streams model that are not
  available in Common Lisp streams, such as line buffering, which are
  neither pretty nor easy to request from Common Lisp and consequently
  cause the Common Lisp environments to lack these features.
