--pidoption is set, pid file is written at https://github.com/ros/ros_comm/blob/lunar-devel/tools/roslaunch/src/roslaunch/__init__.py#L257 but codes for removing written pid file is underif-elsecondition (so there can be conditions thatroslaunchprocess dies but pid file is left without removal)This pull request moves the code for pid file removal to main
try-except-finallyblock so to ensure pid file is removed if exists.
