In (most?) PBS deployments, you don't end up in a slow queue - you get 
your job rejected. Queues are selected by specifying a queue name, 
separately from the walltime.

This requires low-end users to have a better understanding of the submit 
stack than even someone like you who has worked on grid stuff for many 
years has; I think thats a nice argument for not compelling this.

That could be implemented but feels a bit messy to me - if you know what 
the time to specify is for your apps, and can take a max() of it to set 
the default, then you also have enough understanding and information to 
specify it in tc.data.
