 When using GridModule, I am getting error:

 AttributeError: 'VisibleMapset' object has no attribute 'write'

 }}}

 This happens probably when the SEARCH_PATH is not defined in the mapset.

 Also, If I then set it and run successfully the process in parallel, the
 search path is changed, it includes all the mapsets in that location,
 which shouldn't happen.
