//
// When disabled, dispatch happens eagerly in batch, so when a binding is
// scheduled to dispatch messages, it fully flushes and dispatches all queued
// messages within the extent of a single scheduler task.
//
// Enabling this feature allows for more fine-grained performance control
// through the scheduler, but may initially cause some important edge cases to
// regress in performance due to high-priority messages seeing increased
// latency. Ideally we'd address these cases by giving the affected bindings
// higher-priority TaskRunners.
