Re: Emacs - cannot connect to X server

    I do not understand how emacs connects to the X server, but I am suspicious
    of timeouts.  Could it be that emacs does not wait long enough to establish
    an X-session over a slow link?

It IS possible, because Emacs (on some systems) gets alarm signals
regularly to "poll for input".  Perhaps the signal causes a problem
of not "waiting" enough.  (I'd say that is a bug in Xlib if it happens.)

Could you see if this patch makes the problem go away?
It may not be something we really want to install, though.
