This seems a bit dangerous.  I have at least one old system that
uses dd to continously read the kernel message buffer in the
background, and there's tons of other potential dd uses.

Given that we now require bash and bash has array support you might
be able to store the pids of "our" dd instances in an array and
loop over them.
