Content
concurrent.futures uses polling in its worker threads and processes (with a timeout of 0.1). It means that: 1) this prevents CPUs to enter low power states durably 2) it incurs latency when calling shutdown() on an executor (this seems to be the main source of slowness in test_concurrent_futures under Linux)
