 // some Windows bots. I don't recall ever seeing flakes on other bots. At 30 ms
 // tests seem reliable on Windows bots, but not at 25 ms. We'd like this timeout
 // to be as small as possible (see the description in the .h file).

 // Currently, |tiny_timeout()| is usually 100 ms (possibly scaled under ASAN,
 // etc.). Based on this, set it to (usually be) 30 ms on Windows and 20 ms
 // elsewhere.
