/tmp/.ICE-unix weirdness caused GNOME to run w/ umask 000

I'm still trying to figure out what caused this, but somehow
the /tmp/.ICE-unix directory on this system got into a state
wherein the socket that usually lives there during a GNOME
session couldn't be created. This had the effect of making
GNOME run w/ umask 000, causing all files created by that
session (such as stuff under $HOME/.gnome, and files created
by shells opened as xterms or gnome-terminals) to be
Exiting GNOME, removing the /tmp/.ICE-unix directory, and
letting GNOME recreate it solved the problem.
This one is a bit odd because even during the malfunction,
/tmp/.ICE-unix was mode 1777 and owned by my UID and GID.
"_IceTransMakeAllCOTSServerListeners" failing with error 17
I'm not sure what component of GNOME is at fault here (the
session manager perhaps?) but I know it happens somewhere
after gdm starts the session. (I switched to xdm and got the
I've just confirmed that after:
1) removing /tmp/.ICE-unix
2) starting GNOME, letting it recreate /tmp/.ICE-unix
3) exiting GNOME
4) starting GNOME again
the problem reoccurs.
The errors in .xsession-errors are:
_IceTransSocketUNIXCreateListener: mkdir(/tmp/.ICE-unix) failed, errno

they should be created with care in case someone is

The /etc/cron.daily/tmpwatch may also be affected, as
well as tmpwatch itself since it should not destroy

/etc/rc.d/init.d/xfs is written. It could be excluded
from this, or not (for uniformity).
To reproduce the problem, just install 6.0 + all current
patches and, as a regular user, try to use gdm to start
a gnome session twice in a row. (Don't apply the fix
to see the unwanted behavior!!) Then look at the
