> Citing IGNITE-23716:
> 1. IgniteAttachmentLock writes to shared location both for sync and async
> paths - it should be striped in some way.
> 3. IgniteSpinBusyLock duplicates VersatileReadWriteLock in many aspects and
> vice versa. I believe ISBL can be replaceĐ’ with VRWL.
> See for example org.apache.ignite.internal.util.IgniteUtils#inBusyLockAsync
