:mrdocs:

Configure this pool with the specified non‐negative `backoffLevel` that controls the amount of spinning that occurs when calls to this pool encounter contention. Setting `backoffLevel` to 0 disables spinning. Greater values of `backoffLevel` correspond to greater amounts of spinning. The behavior is undefined unless `0 <= backoffLevel`. Note that both contention detection and spinning strategy are implementation defined.
