A small number of the tests in LayoutTests/storage/ call window.layoutTestController.clearAllDatabases().  This function deletes all databases in the current profile.

This is a good idea; the theory is that tests get a clean slate from which to start.  Ideally all database tests would call it before doing anything, so as to avoid any quota problems from leftover databases.

However, this is a terrible thing to do if you might be running in parallel with other database tests; you can interfere with any other test that's trying to create or use a database.  We're going to need a way to mark these tests as non-parallelizable in order to be able to run them safely under new-run-webkit-tests.
