5	  Before sleeping waiting for a request (GPU operation) to complete,
6	  we may spend some time polling for its completion. As the IRQ may
7	  take a non-negligible time to setup, we do a short spin first to
8	  check if the request will complete in the time it would have taken
9	  us to enable the interrupt.

12	  the cost of enabling the interrupt (if currently disabled) to be
13	  a few microseconds.
