What do you mean by LoadableObject functionality? The actual loading
could well be handled by movie_root, as the Timer and threading method
is hopelessly wrong (as well as ugly) - events are wrongly timed at the
moment and impossible to control as needed. A failed load, for instance,
should not be signalled immediately, and there *are* movies that rely on
this (including our LoadVars test in misc-ming.all). I think we still
set the loaded property to true even when the load fails, but the whole
thing is so broken that I've never bothered changing it.

LoadableObject itself just represents an abstraction of XML and
LoadVars, and aside from removing the typing from load() (and any other
methods that are tested to be generally applicable), I don't see what
needs to change.
