[leveldb] iterator traversing and data created in between

[Benoit Chesneau]

Like I understand the iterator is capturing last sequence and then return
each K/V where the sequence of the Key is less or equal to it and skip
others. But what happen when many new K/Vs are inserted in the range and we
didn't go over then yet. Will it also skip them until it find a good K/V
to return? Or is there some mechanism that makes the iterator completely
isolated from updates?
