After load_image() the new team's main thread isn't running yet, so it
can't have created a BApplication yet. If you resume it immediately, you'll
at least have a race condition. BRoster::Launch() employs darker magic
though, which will allow you to target the application immediately after it
returns (in fact even if it never creates a BApplication at all).
