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,
