Anand, nice find..

But i read this in python docs -

"  Warning
Assigning the traceback return value to a local variable in a function that
is handling an exception will cause a circular reference. This will prevent
anything referenced by a local variable in the same function or by the
traceback from being garbage collected. Since most functions don’t need
access to the traceback, the best solution is to use something like exctype,
value = sys.exc_info()[:2] to extract only the exception type and value. If
you do need the traceback, make sure to delete it after use (best done with
a try ... finally statement) or to call exc_info() in a function that does
not itself handle an exception."
