# 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.
