 A file can not be removed as long as it is kept open by some application.
 This is a universal feature I guess. At least it applies to Linux and MS
 Windows.

 I see two possibilities to fix this QGIS bug:

 1. QGIS must close all corresponding files once it has finished rendering
 a GRASS vector or raster map. It can still be displayed in the QGIS canvas
 after rendering but the files must be closed.

 2. The QGIS-GRASS plugin handling of g.remove and g.mremove (and pretty
 much all modules producing an output raster or vector map) must make sure
 that the maps to be deleted (or overwritten) are not kept open by QGIS.

 Closing this ticket because it has been confirmed to work with GRASS and
 remains a problem with the QGIS-GRASS plugin.
