It will be there about five minutes after it's done :-)
In summary, I have hread support fully implemented in the inner loops,
but it's a bit complicated to combine it with MPI parallelization in
the neighborsearching, not to mention PME.
Second, for a lot of systems (large ones) you might actually get better
performance from splitting it and using MPI parallelization instead.
The big feature with threads will be the easier automatic load
balancing, but that's not working yet...
