While the API is hard to change, we could still use a bit more telling
variable names, like diskUsage and oldDiskUsage. Just a not, and if I would not
had noticed below tiny potential bug, I might have just fixed this up locally.

this is never true vor the case where one is defined and the other
value is undefined though, as the result then is NaN. But, when old is
undefined and new isn't we probably always want to trigger a change event?
Might be enough to add a extra branch like:
} else if (typeof diskUsage !== typeof oldDiskUsage) {
changed = true;
}
