Just so I understand, if we have a console (DOS command window for
example) then will dropping CREATE_NO_WINDOW result in a new window or not?
One thing that it does highlight is that the coverage for inherit in
ProcessBuilder/Basic.java was not sufficient as this should have been
caught a long time ago. My preference would be to add to this test
rather than introduce a new one (ProcessBuilder.java is Martin's
original mother-of-all tests for ProcessBuilder).
