It's not even clear that the array needs to be dynamically resizable (yet).
Compare for instance syscache invalidation callbacks, which have so far
gotten along fine with a fixed-size array to hold registrations. It's
foreseeable that we'll need something better someday, but that day
hasn't arrived, and might never arrive.
I agree with the feeling that this patch isn't done if the "core"
timeout code has to know specifically about each usage. We have that
situation already.
