OK, I guess I see the problem now: Figure.suptitle really should be able 
to replace a prior suptitle, and the most straightforward way to 
facilitate this is with an explicit reference kept by the Figure.

Why should a reference be kept other than that in self.texts? Instead 
of keeping track of it somewhere else, would it be sufficient for the 
suptitle method to add a default "suptitle" label to the text object? 
Is there really anything special about the "suptitle" compared to any 
other text object that might be placed on the figure?

Does not reply to the list by default (?), so reposting
Ah, thanks for pointing out the reference in self.texts. I can use
this. I don't have time for a patch now, but I filed this issue.

Correct, this still seems to be the case. Looking at the code in
figure.py, the suptitle() function just creates a text object and places it
at a default location. Then it simply returns the object without saving a
reference to it being a figure title. The only reference kept is in the
self.texts list that it keeps. I see no reason why it has to be this way,
though, and would certainly welcome a patch to fix this oversight (would
make the code involving bbox_tight to be more simple, I think.

Is there a way to overwrite suptitle? When using 3rd party libs that
return a figure, if they set suptitle and don't give you the text
object back then you can't overwrite it? This doesn't seem right to
me.
