> There are a few places in the code (sink_node.cc, source_node.cc,
> file_base.cc) where the backpressure counter is of type `int32_t`. This
> prevents `ExecNode::Pause(...)` and `ExecNode::Resume(...)` from being
> thread-safe. The proposal is to make these backpressure counters be of type
> `std::atomic<int32_t>`.
