Me or someone on our team will work on it.

I'm not sure that subtracting the spin time is the optimal thing to do.

The busy poll time is supposed to be limited to something less than 1ms.
(I'm using 50us in most of my tests)
This is typically orders of magnitude smaller than the poll timeout.
Would it make more sense to just enforce a limit on poll time?

What do you think?

Thanks,
Eliezer
