 a bit >excessive.

 That must be a recent development .  I was able to use r.in.lidar on 7  x
 3.3 billion point las files simultaneously on an 8 core computer to point
 count and calculate range  range using the 2012_04_21 svn snapshot without
 excessive memory use.  How big was the region and how many cells were you
 trying to process into?
