OK, no blocking I/O!

Well here is how we'll make a final determination about sandbox paths. Paths can contain < and > and : and | and even embedded \0 characters. This is a good argument for adding an #ifdef in the LaunchOptions. Also, be sure to pass the path through WebCore::Filesystem::stringFromFilesystemRepresentation. Programming is hard; too many things you have to remember. :S
