I apologize for the confusion regarding the "Pipe " class.
There is a conditional declaration of the "Pipe" class, one for windows and another for non-windows host platform. My confusion was whether I should move both of them or not.
Now I have moved both the "Pipe" classes into common location "lldbgdbserverutils.py" and pushed it.
