Subject: [PATCH] Fix unclosed Session file descriptor leak in RequestsClient
 (fixes #874)

Register atexit handler to close thread-local Session when Python
exits. The Session created in _thread_local is never closed, causing
ResourceWarning and socket file descriptor leaks.

Fix: add atexit.register(self.close) in RequestsClient.__init__.
