// We use a different origin than other webapps test files because we compare
// the number of apps before and after installing this one; and if a test file
// installs our app and then doesn't uninstall it (f.e. because it isn't written
// to clean up after itself, or because it throws an exception or times out),
// then this test will *reinstall* the app, and the number of apps won't change,
// which will look like a failure in this test although it's actually a failure
// in the other one.
//
// Using a different origin here isn't a foolproof solution, as another test
// could start using it. Reviewer vigilance is required! And to anyone reading
// this: don't use this origin without good reason and due consideration for
// the potential consequences!
//
// Alternately, we could define a test-specific domain, getNotInstalled.com,
// in source/build/pgo/server-locations.txt. But that seems like overkill,
// and this problem will go away once we support multiple apps per origin,
// since then we can make this test install its own personal webapp from any
// origin.
