The matplotlib figure is contained in a FigureCanvas which is
contained in a FigureManager, and the manager has a method to set the
window title:

  fig.canvas.manager.set_window_title('some title')

unfortunately, there is no method provided to *get* the window title
for reuse later by savefig (we need to add it).  You can, however, use
the figure label (all matplotlib artists from lines, to text, to the
axes to the figure have a label property.  So something like this
should work

    import matplotlib.pyplot as plt
    fig = plt.figure()
    title = 'some title'
    fig.set_label(title)
    fig.canvas.manager.set_window_title(title)

and later:

    fig.savefig(fig.get_label())

Hope this helps,
