Per http://docs.python.org/2/library/os.html#os.getlogin, getlogin() only works when you have an associated controlling tty. This script didn't work previously because when we do deployments there is no tty. Thus, we switch to the alternative mechanism for determining the current username described on the page linked above. (imported from commit 1dbcf98fd7248d20e501fd7fb22e1dbd306040fd)
