I recently came across the need to spawn multiple threads, each of which needs to write to the same file. Since the file will experience contention from multiple resources, we need to guarantee thread-safety.

NOTE: The following examples work with Python 3.x. To execute the following programs using Python 2.7, please replace threading.get_ident() with thread.get_ident(). As a result, you would need to import thread and not threading.

1. (The following example will take a very long time). It will create 200 threads, each of which will wait until a global lock is available for acquisition.

# threading_lock.py
import threading
