If I understand the logic here, we're checking before emplacement if an
interrupt is needed and then once we emplace we Interrupt,
- Why are we setting interrupt needed when callbacks is empty?
- Should we invert this where we trigger the interrupts before a potentially
long emplace (this is in response to my nanoseconds fidelity question)
