[pygame] vidmod hang in pygame.init()

[<mazer@socrates.berkeley.edu>]

Hi -

I just noticed that pygame.display.init() seems to hangs when called
opening a display on a remote server under X11.  Has anyone else
noticed this problem?  Platform is intel redhat 6.1/7.1/7.2 using a
recent CVS snapshot of SDL and a moderately recent cvs snapshot of
pygame 1.2.  It's easy to reproduce; the following works fine when
$DISPLAY is local (:0.0), but fails when it's a remote machine. That
is, you've rlogin/xon'd to another machine are are running python
remotely and asking SDL to connect back to your display, so
so DISPLAY is NOT :0.0

% python
Python 1.5.2 (#1, Jul  5 2001, 03:02:19)  [GCC 2.96 20000731 (Red Hat Linux 7.1 2 on linux-i386
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import pygame
>>> pygame.display.init()
..python's completely hung now..

It's hanging inside a select call when SDL is quering the X server
for valid display modes.  I can supply more info, but I have a funny
feeling this used to work fine and I must be just missing something..

Thanks,
