> Currently each forked jvm has cwd = tempDir = .
> This provides some minimal protection against tests in different jvms from interfering with each other, but we can do much better by splitting these concerns: and setting cwd = . and tempDir = ./temp
> Tests that write files to CWD can confuse IDE users because they can create dirty checkouts or other issues between different runs, and of course can interfere with other tests in the *same* jvm (there are other possible ways to do this to).
> So a test like this should fail with SecurityException, but currently does not.
> {code}
> public void testBogus() throws Exception {
>   File file = new File("foo.txt");
>   FileOutputStream os = new FileOutputStream(file);
>   os.write(1);
>   os.close();
> }
> {code}
