The other point is that since we track the time a chunk takes, it seems strange to not have any knobs to deal with problems in that area. New webrev: http://cr.openjdk.java.net/~tschatzl/8197932/webrev.2to3 (diff) http://cr.openjdk.java.net/~tschatzl/8197932/webrev.3 (full) Looks good! Thanks, Stefan In this webrev I also did some somewhat messy looking renaming of nTAMS to TAMS (removing the n) and passing the (n)TAMS around in conjunction with the bitmap. This will make a follow-up change a lot easier to read. Thanks, Thomas
