title: Chromedriver not deleting scoped* dir in temp folder after test is complete
body: <p>With latest chromedriver.exe running into out of disk space issues as chromedriver is not deleting the folder named scoped_* at the end of the execution. It is occupying almost 20 GB of space for 400 tests. I tried with both 2.28 and 2.29 versions of chromedriver. I am exiting the driver properly with driver.close() and driver.Quit() too. Chrome browser version is 57.</p>
