OK, my report from this afternoon was written in the office, where I have mpl 
0.71.  I'm now home, and my laptop runs 0.70.  Here, I don't see the problem 
at all.  I can't test here the big code where I saw the massive mayavi 
breakdown, because that was written by my officemate.  But at least I can 
confirm that 0.70, whose show() looks like:

def show():
     """
     Show all the figures and enter the gtk mainloop

     This should be the last line of your script
     """
     for manager in Gcf.get_all_fig_managers():
         manager.show()
     import matplotlib
     matplotlib.interactive(True)
     #os.environ['PYTHONINSPECT'] = '1'
     if show._needmain:
         Tk.mainloop()
         show._needmain = False


does not show the spurious prompt thingie (note the PYTHONINSPECT thingie is 
commented out).  I'll try to make this change to 0.71 and test the larger code 
with the mayavi problems, but it may be a few days before I can do that.

HTH,
