Let one AE2 crafting CPU hold several crafting jobs at once. One order runs per tick, and while it runs it behaves exactly like a vanilla single-job CPU.
Vanilla AE2 gives a crafting CPU one job. Want two things at once? Build a second CPU — a second set of crafting storage and co-processors, just to queue. Scheduler Core adds a Scheduler Core block: install it into a crafting CPU multiblock and that CPU accepts several orders at once, sharing itself between them in whole-tick time slices.
