Oh right, my bad. It's been a while...

Anyways, this should either work immediately or fail. Aside from
getrandom(2), which we aren't using here, nothing related to this stuff
should ever block, and if it does then it's a bug we need to work
around.

So, I suggest we add a 1 second timeout to this read.

I can work on that next week.
