$ man mknod ?

  The main issue with a named pipe is that if it ever blocks, the server
blocks, too.  See any number of messages on this list asking why the
RADIUS server stops responding when the SQL server is down...

  If the writes to the named pipe are non-blocking, that's better.  But
it means that data will be lost when the reader of the pipe disappears.
