If the thread on the local computer freezes, you can't blame the other end
of the TCP connection for it. Sure, it might never receive a response from
the other end... but you can set timeouts for those operations to prevent
the thread from blocking, use `select` or one of its variants, use
asynchronous I/O, or interrupt the I/O operations by sending a signal.
There are a lot of options other than leaking threads. This is the first
time I've ever heard of someone other than a novice acting as if not
leaking threads is some kind of hardship for them.
