I posted an example called embedTest.py at http:// 
www.thelostserver.com/embedTest.py.  It is a simple tabbed console.   
On NetBSD, when we type "exit" in any of the consoles, we get the  
"Bad file descriptor" error.

On Mac OS X we can't get it to load at all.  It starts to load and  
then just hangs.  We then tried running your pyqonsole example and  
got the following error:

Do you know of anyone that has pyqonsole running on a Mac or Windows  
machine?
