> This sequence of events is possible:
> # Agent sends register message M1 to master.
> # Agent register timer expires, sends register message M2 to master.
> # Master sees M1 and adds agent with ID A1.
> # Agent gets SlaveRegisteredMessage with ID A1.
> # The master <-> agent socket breaks; the master marks the agent as disconnected.
> # Master sees M2; since the agent is currently disconnected, the master removes A1 and adds the agent with ID A2.
> # Agent gets SlaveRegisteredMessage with ID A2. Since this is unexpected, the agent exits ("Registered but got wrong id").
> Shutting down the agent is unfortunate, although arguably not catastrophic.
