Well, that was about the least fun that I've had in a while.

The magic numbers that I came up with that allowed me to login to GDM, but
not run firefox were:

root - stack unlimited
root - as unlimited
dbus - stack unlimited
dbus - as unlimited
gdm - as unlimited
gdm - stack unlimited
*       -    stack   262144
*       -    as      4194304

This doesn't appear to be a ratio and the system only had 4G RAM but
anything but this pretty much tanked.

Any vendor driven advice would be great but I think it's going to be one of
those "set to what your system needs" adventures.

Thanks,

Trevor
