// On Windows, a sleep_for of less than about 16 ms effectively calls

// Sleep(0). The MS standard thread implementation uses a system thread

|
// pool, which can deadlock on a Sleep(0), hanging not only the secondary
|
|
// thread but the entire test. I increased the delay to 20 ms to ensure
|
|
// Sleep is called with a delay greater than 0. The deadlock potential
