We do not want to wind up on Adobe's schedule -- the problem is on Adobe's
end, not ours, and we cannot even send them a fix. The behavior of memcpy for
overlapping ranges is not even defined, so there should be nothing stopping us
from using a new implementation of memcpy. The fact that a lot of people use
the Flash plugin makes it even more important for *Adobe* to fix what can only
be described as a bug in Flash, which is the current reliance on undefined
