[vtkusers] Aborting observers in python

[Wayne Christopher]

I saw a discussion from a few years ago - 
http://www.vtk.org/pipermail/vtk-developers/2007-September/004725.html - 
about setting the abort flag in an observer to prevent further observers 
from being fired with the python bindings.

Has anything been done about this?  I couldn't quite tell from the 
discussion whether there was a workaround or not.

Thanks,

     Wayne
