Hi Jarno, There's been a few iterations. The previous 64-bit version was using a 32-bit hash combined with a thread ID.
The 128-bit hash was based on a suggestion to have sufficient bits to randomly generate the identifiers, however I've since shifted to using the hash of the flow key---This allows us to remove some backwards compatibility code. I haven't looked at whether a smaller hash would be sufficient, perhaps 128 bits is overkill now.
