Bug report for Octave 2.1.19 configured for i686-pc-linux-gnu

Description:
-----------

  Unplug ethernet connection.
  Start octave. It freezes after displaying the usual

======================================================================

  and before showing the prompt. 

  Also, if I unplug ethernet while octave is running, it
freezes. Sometimes, it will "come back" if I re-connect.

  By "freeze", I mean not respond to ^C or ^D.

  By ethernet connection, I mean coaxial cable used for networking.

  I suspect this is not an Octave bug, but that's the only program for
  which I noticed this behavior.


Repeat-By:
---------

   unplug ethernet cable.

Fix:
---

  plug back ethernet outlet !
