History
Robin Burchell 99dd60611f Kernel: Fix select with a 0 timeout 
select essentially has 3 modes (which is presumably why we're finding it
so hard to get this right in a reliable way :)).

1. NULL timeout -- no timeout on blocking
2. non-NULL timeout that is not zero'd -- timeout on blocking
3. non-NULL but zero timeout -- no blocking at all (immediate poll)

For cases 1 and 2, we want to block the thread. We have a timeout set
only for case 2, though.

Case 3 should not block the thread, and does not have a timeout set.
