Not true, the OS would still close the TCP stream.

The OS will close them.  The case you're thinking about is more when the
OS crashes or you have a power outage.

Timeout is the correct answer.   In order to handle this possibility,
you as the application developer must specify a timeout option to ensure
that TCP connections will eventually be closed by MHD.

See MHD_OPTION_CONNECTION_TIMEOUT in the header/documentation for details.
