Or perhaps at install time a few additional questions are is asked and the
appropriate defaults are adjusted accordingly during the install e.g. how 
many processes are expected during peak times and whether the expected 
loads are IO or CPU bound?

Of course, this would be just the starting point for tuning as loads &
number of processes change over time, but I agree - the default quotas
were defined back when typical memory sizes were measured in MB,
not GB or even now TB (v8.4-2 supports 1.5TB memory on hi-end blades)

In addition, to your point about guarding against rogue processes, I 
would also like see additional enhancements made to the sysman class
Scheduler (SYSMAN> help class)
