I don't think it every is going to scale.

MVCC/TL2 based STM designs rely on a central clock, so if you can
update the clock in 0.1 ms on all machines, the maximum throughput is
1/0.0001 = 10.000 transactions/second... no matter how many machines
you throw at it. Even on a single machine the central clock can cause
scalability problems (10/20M transactions/second and this will degrade
when you throw more cores at it).

This is one of the reasons I dropped the TL2 approach for Multiverse
and switched over to the SkySTM model (with some magic of my own) that
doesn't relied as much on a central mechanism.
