---------------------+---------------------------
 It's not clear what effect these mutations may have on the test process
 itself but they clearly can have an effect on child processes.

 There are two places this happens:

 {{{
 env = kwargs.get("env", os.environ)
 # Python warnings from the child process don't matter.
 env["PYTHONWARNINGS"] = "ignore"
 }}}

 and

 {{{
 env = os.environ
 env['http_proxy'] = env['HTTP_PROXY'] = "http://127.0.0.0:12345"  #
 invalid address
 }}}
