In fact, I see it does work... sort of. For me, with 0.91.2-2 (debian)
asking axhline throws up an error:

/usr/lib/python2.5/site-packages/matplotlib/pyplot.pyc in
axvline(*args, **kwargs)
   1358         hold(h)
   1359     try:
-> 1360         ret =  gca().axvline(*args, **kwargs)
   1361         draw_if_interactive()
   1362     except:

/usr/lib/python2.5/site-packages/matplotlib/axes.pyc in axvline(self,
x, ymin, ymax, **kwargs)
   2330
   2331         trans = mtrans.blend_xy_sep_transform( self.transData,
self.transAxes )
-> 2332         l, = self.plot([x,x], [ymin,ymax] , transform=trans,
scaley=False, **kwargs)
   2333         return l
   2334

and doesn't immediately update the plot (which is what had me thinking
it wasn't working). The plot is, however, correctly updated when a
redraw is forced, such as uncovering the window after writing the
previous email.
