    24 // We use a different origin than other webapps test files because we compare

    25 // the number of apps before and after installing this one; and if a test file

    26 // installs our app and then doesn't uninstall it (f.e. because it isn't written

    27 // to clean up after itself, or because it throws an exception or times out),

    28 // then this test will *reinstall* the app, and the number of apps won't change,

    29 // which will look like a failure in this test although it's actually a failure

    30 // in the other one.

    31 //

    32 // Using a different origin here isn't a foolproof solution, as another test

    33 // could start using it.  Reviewer vigilance is required!  And to anyone reading

    34 // this: don't use this origin without good reason and due consideration for

    35 // the potential consequences!

    36 //

    37 // Alternately, we could define a test-specific domain, getNotInstalled.com,

    38 // in source/build/pgo/server-locations.txt.  But that seems like overkill,

    39 // and this problem will go away once we support multiple apps per origin,

    40 // since then we can make this test install its own personal webapp from any

    41 // origin.
