Title:
  ssl test failures with openssl >= 3.4.0

Status in python-eventlet package in Ubuntu:
  Fix Released

Bug description:
  Currently blocking the build of this package in plucky-proposed - it
  looks like the behaviour between Python 3.{12,13) and openssl has
  changed a little - tests are expecting a SSLZeroReturnERror and a
  SSLError is thrown instead with "[SYS] unknown error".

  openssl 3.4.0 is currently in proposed; I've tried with older openssl
  versions and the newer pythons and the previous behaviour is observed.
