Alex Crichton 6afa32a250 std: Don't always create stdin for children ... For example if `Command::output` or `Command::status` is used then stdin is just immediately closed. Add an option for this so as an optimization we can avoid creating pipes entirely. This should help reduce the number of active file descriptors when spawning processes on Unix and the number of active handles on Windows.		2016-03-08 17:45:44 -08:00
