Subject: [PATCH] fix(delay): write pending state once per node in batch checks

checkListDelay pre-marked every node as checking, help() re-marked it
when picked up and measureDelay marked it a third time on entry, so
each batch run queued three identical pending updates per node. Keep
the pre-mark (immediate feedback for queued nodes) and drop the
redundant marks along the chain.
