Hello James,
I made the following changes in check_lock()

def check_lock():
-    try:
-        fcntl.lockf(get_lock_file(), fcntl.LOCK_EX | fcntl.LOCK_NB)
-    except IOError:
-        return False
-
-    return True
-

+       pid = os.getpid()
+       try:
+            fcntl.lockf(pid, fcntl.LOCK_EX | fcntl.LOCK_NB)
+       except IOError:
+           return False
+       try:
+           os.kill(pid(), 0)
+       except OSError:
+            return False
+        return True

so that when there is no process running false is returned. However it is
not fixing the bug.
And yeah when I try to delete the lock file, I get 'file or directory 
doesn't exist'

Sorry for the novice questions :(

Kind Regards,
Shraddha
