I will do that.

(Disconnections can not be prevented entirely, though: Emacs/GTK crashes
on both branches if a server connection is cut or a server crashes.  In
some use cases, this happens regularly, by design: e.g., if the user
runs emacsclient to create a frame on an ssh-forwarded remote X server,
then later logs out from the ssh session, the server connection is
closed, unintentionally SEGVing the Emacs process.  I think we should
document this in PROBLEMS.)
