Python でブロッキングソケット関数呼び出しの実行時間を制限するにはどうすればよいですか?

import signal
import threading

# Define our target function that may potentially block
def long_function_call():
    while True:
        # Some operations that may consume a lot of time
        pass

# Define a function to handle the timeout signal
def signal_handler(signum, frame):
    raise TimeoutException("Timed out!")

# Create a thread that will execute the function
thread = threading.Thread(target=long_function_call)

# Register the signal handler to the thread
signal.signal(signal.SIGALRM, signal_handler)

# Set a timeout limit (in seconds)
signal.alarm(10)

# Start the thread
thread.start()

# Wait for the thread to complete or time out
thread.join()

# Handle the timeout exception, if any
if thread.is_alive():
    print("Timed out!")
