Do you mean paging in general or thrashing?
I always thought: paging good, thrashing bad.
A good effecient paging system, always moving data between memory and disk, is great. It's when you have the greater than physical memory working set that things go to hell in a hand basket.
Did Linux ever do the old trick of "We've too much going on! You! (randomly points to a process) take a seat! You're not running for a while!" and the process gets totatlly swapped out for a "while," not even scheduled?
