Yeah, like the head block, it's a copying operation. But that's
"relatively cheap". |
I'm not quite sure about the state of this, but at GRCON '14 work
was started on letting blocks define where their buffers are –
maybe, one day, as a side effect, we can actually use the same
buffers for in- and output and get rid of the copying.

If we wanted that behavior, could we do something
similar to what gating blocks do (like the power squelch), where
we pass X number of items through and after that only consume
items without ever producing anything. Is there an efficiency
problem with this technique?
