> htraced has a bug with greater_than queries.
> Leveldb exposes a sorted map interface. It supports seeking to a specific
> key, but not to a position "greater than" a specific key. The code right now
> for greater_than assumes that if after the leveldb seek, it sees an
> equivalent key, it only needs to do one step forward to get to the keys which
> it should be able to return. However, it there are multiple "equal" entries,
> greater_than may have to do multiple seeks.
