Something along those lines, yeah. You could e.g. have an application
that does redundant InitFromFile() calls inside of some hot-path
because instead of keeping track of whether the texture is initialised
it depends on InitFromFile() failing quickly. Note that that only
works if it fails quickly on Windows as well, and leaking the
IDirect3DRM reference on each failed call makes the scenario a bit
unlikely.
