What happened to the row level locking efforts?

Hi,

maybe I missed something.

There have been some efforts around 2008 to give the memory storage engine some row locking capabilites.
There was this one on topcoder:

and apparently also some kind of competition:

but I could not find any results from these.

Yes I saw the hints to replace Memory Engine with MySQL Cluster. But this heavyweight thing requires installing three nodes on one server and then has capabilities that never will be needed for the volatile data Memory engine was made for, but surely have impact on performance.

Now can anybody tell what happened to the row lock topics?
