it would be the same way we handle the initial login that establishes
the ssh tunnel... so i don't see any special need to handle any sessions
or window managers... it happens after the Xsession script has completed
(because the "ltspfsmounter all cleanup" part does execute).

although, scotty suggested using the xatomwait code from the localapp
stuff, maybe that's even better.

while it doesn't solve the issue for warren, newer ssh versions seems to
fix it for me, so i think there is something to do with the ssh
connection here, more than X or anything done wrongly in ldm. 

i've seen the same behavior from code i wrote in 2003 (sdm).

i think we'll need to work around the issue, even if it may just be
misbehaving X applications... because we can't fix every X application
out there just to have LDM work properly.

for debian, i wrote a patch to ldm 2.0.6 that makes it a configurable
option... not ideal, but at least it's possible to get either behavior.

live well,
