This is the expected functionality of linecache. As each file is read, it is stored in a cache, subsequent calls using linecache do not check to see if the file has changed.

If you know that the file has changed, you should call linecache.checkcache() to check all files or linecache.checkcache(filename) to check a specific file. (https://docs.python.org/2/library/linecache.html#linecache.checkcache)
