The platform generally tries to eliminate the possibility for race
conditions whenever possible.  It's not always possible, of course, but
adding a new category of races should be thought about carefully,
especially if all it takes to trigger it is "img1.src = img2.src = url".

Can you give a specific example?  If there are cases where the spec allows
this to happen, it would help to see whether that's intentional or
something that should be fixed in the spec.
