Comment (by glynn):

 Replying to [comment:4 hcho]:

 > os.environ!["GRASS_REGION"] is passed to r.what correctly only for the
 *first* query. After that, r.what cannot see any changes to this variable.
 Now, I'm puzzled...

 Please don't use os.environ for per-command environment settings.
 subprocess.Popen() has an "env" parameter; use it!
