Comment(by hamish):

 as MarkusM asked, what does `g.region -p` say?

 can you turn debug level to 2? (`g.gisenv set="DEBUG=2"`, then back to 0
 to turn it off)

 for a 3000x3000 computational region and method=mean it should use
  3000*(3000+1)*4 * 2 / 1024000 = 70.3 MB
 of RAM to hold the data, and complete in just a few seconds.

 does `las2txt | r.in.xyz input=-` work? (see LIDAR page in the grass wiki
 for correct usage)
