Though it offends one's engineering sensibilities[1], it's just not
that inefficient. I'd bet money you won't even be able to measure the
difference in CPU usage. Waking up twice per second and immediately
calling select() again on any hardware/OS built in the past 50 years
is going completely negligible (as long as you can ignore the smell).

Even waking up ten times per second won't be noticeable.

Waking up every millisecond or two might be noticeable.

Agreed.

[1] If offenses to engineering sensibility were of concern, then
    he wouldn't be using Windows in the first place.  ;)
