Checking network input processing by Python for a multi-threaded server

This data processing style can be generally fine as long as you would like
to work without a thread (or process) pool.

I have taken another look at the implementation of the corresponding methods.
https://github.com/python/cpython/blob/3.7/Lib/socketserver.py#L656

I get an other impression from the statements “self._threads.append(t)” (process_request)
and “thread.join()” (server_close).

Will a corresponding return value bet set?

I am still looking for the support of software constraints in this direction.

Will the development situation evolve any more here?
