Research direction

Start by reading the socket module implementations for getservbyname(), getservbyport(), and getprotobyname(), then inspect the linked PR gh-151850 and the existing extension-module tests. Done means the three APIs behave safely when called concurrently, with regression coverage demonstrating that behavior.
