From 319d541210cf1c5c00d11f8f9bb41dee7d7d8f76 Mon Sep 17 00:00:00 2001 From: "Andrew M. B. Boktor" Date: Tue, 8 May 2012 18:19:15 -0800 Subject: A much easier way to attempt to fix the problem targeted by CL12362 is to just print the stats whenever a kernel is done. This requires decoupling updating the stats from printing them and modifying the printing code to accomodate this change.
