Hi John,

These changes to backend_wx(agg).py seem ok to me.  Trying to 
be conservative, I'm not entirely sure whether having the
SetExitonFrameDelete() call is necessary (or perhaps more
settings for the wxapp should be set....).

What's pylab supposed to do in interactive mode if the user
closes the plot window after show() but then wants to create 
and show() another figure?  Is pylab supposed to automatically
create another window and plot to that new window?  This 
doesn't work for WX.

Yep, that seems useful.
