[Paraview] Threads in the python shell

[Pat Marion]

Dave's right, you can't use python threads in the paraview python shell.
After your while loop exits, control is returned to the Qt event loop and
the python thread has no chance to cycle.  It might work if you try
pvpython instead.

You could also try a plugin I wrote last year...  you have to compile it,
but then you can do everything from python, no additional recompiling.  It
adds UI for creating remote control sockets in the paraview gui, and all
character data received on the socket is executed directly in the python
shell.  I just put it up on github:
