Finalize vs Dispose
...uarantee that a finalizer will execute at all on any given instance.
Never allocate memory in finalizers or call virtual methods from finalizers.
Avoid synchronization and raising unhandled exceptions in the finalizers.
The execution order of finalizers is non-deterministic—in other words, you can...

byte *buckets; // array of 2^B Buckets. may be nil if count==0.
