You mean to treat several rasters at the same time ?

It shouldn't be too complicated to write a wrapper script for this. I 
would imagine the biggest problem to be the handling of the access to 
the attribute database file. Not sure that you can have concurrent 
access to this file by several parallel processes. If this is an issue, 
we would probably have to add the option to output v.rast.stats results 
to text files and then load content of these files into at the attribute 
table of the vector map at the end...
