//  Duplicate the socket to share the same connection across threads.
//  In a multithreaded application, each thread should use its own socket object. For example:

//  - The main thread can use the original socket for reading.
//  - A secondary thread can use a duplicate for writing.
//  - Another thread can use a separate duplicate to monitor the connection status.
