Same breakpoint hit multiple times

[karthiknadig]

Repro code: Python 2.7, set breakpoint on print. It can hit multiple times. This seems like a issue with breakpoint on first line.

print('Hello')

Traceback from first hit:

Taking a look at this (as a note, this seems to be an issue only on python 2.7 and works properly on python 3.6).
