Transaction forwarding could be randomised slightly, by randomising the
outgoing relay order; and adding a random delay between each forward. Even
the massively connected monitor can't represent _all_ the connections on every
real node, so it would have no way of knowing whether it got any transaction
from the originator or because it got a fast path through the first N nodes to
receive it.
