AFAIK, this can also be tickled by a very large message sent between
nodes and the network is "slow enough"(*).  The inet_drv driver may be
busy transferring data in the middle of that message, but that busy-ness
does not affect the ticktime ticker thingie.


(*) It might be that 1Gbit/sec Ethernet or 100Mbit/sec Ethernet is just
too slow to transfer a 3 Gbyte Erlang term(**).  Or you've been bitten
by a congested network that's dropping packets.  Or something else.

(**) This has never, ever, accidentally happened in a Riak cluster, oh,
heavens, no.
