// sending them too fast. For example, if we have a reliable event
// with ID 3 pending, the highest ID we can send would be ID 67. If we
// send an event with ID 68, then the client may ignore ID 3 when it
// comes in for being too old, even though it's reliable.

// In practice this shouldn't be a problem unless we're sending way
// more events than is reasonable(/possible) in a single packet, or
// something is wrong with reliable event acking.
