[Testers Needed] Using non blocking I/O

[barry-scott]

I have been looking at the code and noticed that its was using select is an odd way.
The oddity is that the fd is not set O_NONBLOCK.

The end result of using O_NONBLOCK is that the code will report the temperatures as soon the sensor reports them.
Takes 0.386s vs the old code taking 0.558s. Tested with a TEMPer2.

If you are interest in my refactors let me know and I will raise a PR.

My refactor is in barry-scott@772d8c0.

I am interested in this, but I'll need some testers with the different devices. I have one of the devices, and many of them are pretty finicky.

I don't have to have full coverage of all devices here -- this is entirely volunteer-driven, and it might be hard to get volunteers with all devices. But a decent majority without issues would work for me.

Can you open up a PR for this?

@eode : You should open a PR for this.

[eode]

@neofob you're welcome to open a PR for this.

PRs I'll accept:

• one that handles all models and has been tested with all models

or

• one that provides alternate legacy/current vs new/nonblock code paths, and uses the new code path only for models that have been tested with it.
