The code inside Broadcaster makes usage of iterators using olden C++ coding
style. Hidden in this old style is a couple of N^2 loops: we iterate over a map
(sequentially), removing the first element that matches some predicate. The
search is _always_ done from the start of the map, which implies that, if the
map has N elements and if all matches happen on the second half of the map, then
we visit the first N/2 elements exactly N/2 * N/2 times.
