One comment, one question.

First, I think we should try to integrate this work and then tune it up =
more.  The API
is, I think, fine, and performance tuning takes a bit of work.

Second, what are the parameters set on buffers for the drivers?  I.e. =
how many slots
do they have in their queues etc.?  If they defaults are too small, and =
often they are,
then that's going to hurt your performance.

Best,
George
