a multithreaded process..

Given that 2.7 has now been end-of-life for two and a half years,
I don't think we need such a detailed explanation here anymore of
the differences between Python 2 and Python 3.

Fix a crash in subinterpreters related to the garbage collector. When
a subinterpreter is deleted, untrack all objects tracked by its GC.
To prevent a crash in deallocator functions expecting objects to be
tracked by the GC, leak a strong reference to these objects on
purpose, so they are never deleted and their deallocator functions
are not called.

`IPv*Network` and `IPv*Interface` constructors accept a 2-tuple of
(address description, netmask) as the address parameter.
When the tuple-based address is used errors are not propagated
correctly through the `ipaddress.ip_*` helper because of the %-formatting now expecting several arguments:
In [7]: ipaddress.ip_network(("192.168.100.0", "fooo"))
...
TypeError: not all arguments converted during string formatting
Compared to:
In [8]: ipaddress.IPv4Network(("192.168.100.0", "foo"))
...
NetmaskValueError: 'foo' is not a valid netmask
Use an f-string to make sure the error is always properly formatted.

If the error handler returns position less or equal than the starting
position of non-encodable characters, most of built-in encoders didn't
properly re-size the output buffer. This led to out-of-bounds writes,
and segfaults.

example.com is reserved by the IANA as special-use domain name for documentation
purposes. The domain names are used widely in books, tutorials, sample network
configurations, and generally as examples for the use of domain name.
On the other hand, mydomain.com is real Domain Name Registration service.
