new_merge_durations
is not just a mirror of Index.Stats.merge_durations
, it only contains the new entries since the last time it was recorded. This list is always empty when in the header.

Melting pot of stats, recorded before and after every commits.
They are necessary in order to compute any throughput analytics.
Stats computed from the tree
value passed to the commit operation, before the commit, when the tree still carries the modifications brought by the previous operations.

is now innexpensive to perform.
