Not just for that reason, the geometry is wrong as well. It's especially 
bad when an object can reflect itself and when a surrounding object 
comes close to the mirroring surface.

I'm not sure how much time it'd gain, if any. You'd have to render the 
environment map from the point of view of the object at a resolution 
similar to what you'd get from reflected rays, except you would end up 
tracing rays in directions there aren't actually any reflections of. I 
suspect tracing the environment map will take as long or longer than 
just tracing reflected rays.
