That was just a proposal to be put on the table. :-) Others, especially Vlad of course, have the final say. And I somewhat sympathize with the cautious approach here, because we were forced to downgrade from DF_LIVE to DF_LR for resource.c at some point (but of course it's resource.c so...). -- Eric Botcazou
