OK, unless I hear that someone else is working on one I will take a look at this.

Duly noted.

For the kernel peeps I think this makes a case for revisiting the “big hammer” control for IO polling since it is going to be a while before applications can utilize the preadv2/pwritev2 approach… I will take a look at that too.
