[New-bugs-announce] [issue7207] test_telnetlib fails on OS X 10.6

[Mark Dickinson]

New submission from Mark Dickinson <dickinsm at gmail.com>:

test_telnetlib fails consistently on OS X 10.6, for a default (64-bit) 
build of py3k.  Test output below.

It looks to me as though this is just a race condition in the test 
(possibly combined with socket-related peculiarities of OS X) rather 
than a problem with telnetlib itself.  I suspect that the 'server' 
function in test_telnetlib.py is getting to the 'serv.close()' line 
prematurely, before all the test data from the 'test_write' test have 
been written.

Jack, I notice you've worked on these tests recently.  Any ideas?
