swap or not?

I'm looking for some opinions (based on real cluster setups would be nice 
too).  If you've got nodes with lots of memory (>1GB) do you run with swap 
space configured or not?

We're seeing the occasional run that misses its memory request by a lot 
and it hangs nodes due to excessive paging.
