One way to do it is to just replace sys.stderr with some class that has 
a write(text) method.  Then it will be called whenever anything (such as 
a traceback) is written to stderr.  From that point you can do whatever 
makes sense with the text, toss it, log it, accumulate it until idle 
time and then display it, etc.
