> It would be useful to have tasks use more than a single pool slot.
> Our use case is actually to limit how many tasks run on a head node (due to memory constraints), currently we have to set a pool limit limiting how many tasks.
> Ideally we could set the pool size to e.g amount of memory and then set those tasks pool_usage (or whatever the option would be called) to the amount of memory we think they'll use. This way the pool would let lots of small tasks run or just a few large tasks.
