 Steps provided with sample fire simulation data
 (http://grass.osgeo.org/download/sample-data/) fails for GRASS 7 (trunk).

 When G7:r.ros is used with `-s` flag it reports `ERROR: Invalid
 descriptor: somenumber`:

 {{{
 r.ros -s model=fuel_model moisture_1h=1hour_moisture
 moisture_live=live_moisture velocity=wind_speed direction=wind_direction
 slope=slope aspect=aspect elevation=elevation output=my_ros
  100%
 ERROR: Invalid descriptor: 11
 }}}

 I'm in demomapset. All output maps are created (my_ros.base, my_ros.max,
 ...) including `my_ros.spotdist` and I can run G7:r.spread.

 It works without `-s` flag:
 {{{
 r.ros model=fuel_model moisture_1h=1hour_moisture
 moisture_live=live_moisture velocity=wind_speed
 direction=wind_direction slope=slope aspect=aspect elevation=elevation
 output=my_ros
 }}}

 It seems that the error goes from source:grass/trunk/lib/raster/close.c:

 {{{
 $ grep -Irn "Invalid descriptor" .
 ./lib/raster/close.c:74:    G_fatal_error(_("Invalid descriptor: %d"),
 fd);
 ./lib/raster/close.c:107:    G_fatal_error(_("Invalid descriptor: %d"),
 fd);
 }}}
