I was trying to figure out the right way to get specifics to be added to the work. Technically, we could keep the pending_specific list; this is taking a different approach of inserting inside the work stack, which will do extra work moving entries, although typically that should be expected to be small. One challenge of `pending_specifics` is that if we would need to shift them to work after both `Done` (for immediate processing) and `Retry` (for processing after the current instruction is later revisited and done). That feels kind of awkward as additional tracking to do. Also, the common case is probably that there's either 0 or 1 specifics being added, so an additional vector may be significant overhead. That's why I leaned more in this direction of just inserting them in the vector of work.
