One VERY useful profile parameter in these cases is the CPU_PER_CALL.
I've had this limited down to something like 5 minutes in the past for a
user who could not control their SQL.  If left to unlimited their sql
would run for days.  IDLE_TIME is another good one for those folks who
don't know how to properly shutdown their PC's.

That is very true. Though most of their data comes from individual
tables, occasionally they may join..
I will also put some additional restrictions on their profile. 
Thanks for catching it!

All these thoughts of people who don't know SQL writing SQL, returning
results sets with six-figure cardinalities, ...quite arousing.

Sounds like the opening chapter of an interesting story. :-)

could be to enable dcd (dead client detection, sqlnet.expire_time) in de
