Comment 15 for bug 2055114

FWIW, this is what we did in Fedora: https://src.fedoraproject.org/rpms/fail2ban/c/24c973f252f6d1b4231ee49ee4d5efac785a2fe8?branch=rawhide

i.e., we depend on packages of the asynchat and asyncore libs that were added to pypi for this kind of purpose - https://pypi.org/project/pyasynchat/ and https://pypi.org/project/pyasyncore/ - and we also had to disable a couple of tests. I don't know if Ubuntu/Debian packaged the split-out asynchat and asyncore libs yet.
