merged to master as of 139e32d139103fc7fcb2121146c89edb9f40c55f.

my crappy little test of the OPAL call also merged as of
dd694b530c7b2c28efcae018bca8ad7910f845d8, which I think has been about
enough to convince me to make it easier to run random tests as a

I know we're currently a bit off in having a solid P8 implementation (or
