From 6556534bab10fdd485f3c803321751b6eb9626ce Mon Sep 17 00:00:00 2001 From: Arne Georg Gleditsch Date: Thu, 9 Sep 2010 09:56:19 +0000 Subject: Apparently, it's not crucial to clear this at the exact moment we switch to using ram, so something like the appended is perhaps more appropriate. Confirmed to work on hw.
