Sorry for "butting" in...

I'm just curious about what happened to the thread migration plans or
perhaps I remember that from another project? OpenMosix maybe? As I
understand it thread migration requires shared memory. Of course this
will introduce huge differences depending on the connection between
nodes but can't a NUMA model, perhaps with rDMA, handle such things?
Again, I'm just curious about the subject and don't know much about it...

Hope I'm making some sense...
