This can significantly speed up runs when testing is not CPU-bound.

Thanks @RonnyPfannschmidt! Do you know when that next release will be? |

hmm, #tfw when you respond for the wrong project, definitively time for a weekend @nicoddemus should we do one early next week |

With the change to physical CPU count in #560, test sets that are run with
psutilinstalled and that are not CPU-bound (in my case, with lots of network activity) take roughly twice as long to execute on hyperthreaded CPUs. Add a new choicelogicalfor flag--numprocessesfor use cases like this.This implementation is a bit weird because of the multiple fallback paths in
pytest_xdist_auto_num_workers()which all return the logical CPU count already, but I don't see a better option.Testing:
toxagainst all butpython3.5on Linux:--numprocesses logicalon my six-core hyperthreaded CPU.
