Apparently there is a /dev/shm in my vserver guest.  For kicks, I
changed the group to a group in which the user was a member and granted
write rights for the group to /dev/shm.  Chrome works with this.
However, are there any security issues with allowing vserver guests to
write to their own /dev/shm? Thanks - John
