ZFS WriteThrottling

ZFS had a problem with properly throttling intensive writers like a simple dd if=/dev/null of=/zfs/file which would usually produce "jumpy" writes instead os steady write stream. There is a new way of throttling in ZFS which should solve the problem - I have not tested it yet. The new code was integrated into build 87. Roch has posted a good explanation of the old and the new behavior.
