r.resamp.rst broken in GRASS 7

Description
Running r.resamp.rst fails in 7, succeeds in 6.4.2. In 6.4.2, spearfish, with region set to elevation.dem, this works:
r.resamp.rst --overwrite --verbose input=elevation.dem@PERMANENT ew_res=15 ns_res=15 elev=elev15 Processing all selected output files will require 4719648 bytes of disk space for temp files. Temporarily changing the region to desired resolution ... Changing back to the original region ... Percent complete: dnorm in ressegm after grid before out2= 388.844442 dnorm in mainc after grid before out1= 388.844442 dnorm in mainc after grid before out2= 388.844442 Temporarily changing the region to desired resolution... Changing the region back to initial... r.resamp.rst complete.
In 7 (latest svn up), with region set to elevation.dem:
r.resamp.rst --overwrite --verbose input=elevation.dem@PERMANENT ew_res=15 ns_res=15 elev=elev15 Processing all selected output files will require 4.50 MB of disk space for temp files. Temporarily changing the region to desired resolution ... ERROR: Input window changed while maps are open for read
The error message comes from lib/raster/set_window.c, but the cause may be in raster window handling logic 6/7. This seems to cut in about line 480 in raster/r.resamp.rst/main.c:
Rast_set_window(&outhd);
which calls:
update_window_mappings();
in the library file cited, and triggers the error.

Citation from grass-dev:
In 7.x, the RST library isn't working because it hasn't been updated for the new raster window handling (r40772 etc)
