BTW, this means that my above comment was too hasty; I can't actually
see a situation where we'd ever want to have multiple updates in flight.
Though I also don't immediately see a need to move as the update gets
applied to a specific context anyway and it seems nicer to just stop
using the stream events for anything other than the integration with the
CPU DMA.
