The CPU is at 100% and appears to be making progress.  I suspect that 
if I wait long enough, it will work.  If I renice the job as you 
suggest, then I think this may be manageable.

Alternatively, I have another (fast) machine in my lab that is mostly 
idle.  If I import this vector into Grass using this other machine, 
is there an easy method for transferring this vector from one machine 
to another without having to do the time consuming 'cleaning' again? 
Is there some sort of Grass-object or some other format that allows 
vectors to be moved between machines without having to be reprocessed?

The polygons are very complicated and so I think this is the case. 
I've been able to successfully import other vectors as shape files 
without any trouble.
