Comment (by hcho):

 OK, I think I figured out why it happens. r.what and v.what run in
 GMConsole.cmdThread.RunCmd, and cmdThread takes a snapshot of os.environ
 when it's initialized at goutput.py line 163. No changes made to
 os.environ afterward can be readable by any GRASS modules running in a
 thread. I guess this issue can cause other problems somewhere else.

 Still, I think we shouldn't use GRASS_REGION for r.what.

 Any comments?
