------------------------------------------------
bq.Say we have 99 BBs to be created and we have 10 threads, make 9 threads to
create 10 BBs each and the last one to create 9?
Oh missed seeing this latest comment. So you mean we need to split and then
send it to every callable? So by default always do a split of 10 each?

> If you set bucketcache size at 64G say and then start hbase, it takes a long
> time. Can we do the allocations in parallel and not inline with the server
> startup?
> Related, prefetching on a bucketcache is slow. Speed it up.
