rlogin windows under X11

[david Casperson]

When I rlogin in to watmum or violet from watcauchy using X11 xterm
windows the windows eventually go away, even if i do the EVIL stty
timeout 0 in the rlogin'd window.  Is there a timer somewhere 
of which i am not aware and which i can set to stop my rlogin windows
from disappearing?

For what it's worth, my uninformed guess is that the cause of this
problem is in rlogin, or at least the way that rlogin interacts with X
windows, because other xterm windows started under the rlogin window
don't vanish.
