Subject: [PATCH] Updated gunicorn/pidfile.py

Added a try block to convert the contents of the `pidfile.py` if it can be converted to integer or not. If not, then `wpid` is assigned 0 and the `validate` function returns as usual. If the pidfile has a valid int, the function continues to kill the process as before.
