@clebertsuconic @franz1981 This has been open for some time now. Can you
work together to resolve this, either by merging or closing. If this need
significant refactory/impl work that is going to take some time then I suggest
we close and reopen when it's ready.

> Priority: Minor
>
> It provides a sampling profiler on buffered ASYNCIO/NIO based journals.
> The profiling has a minimal cost in term of CPU time for each sample (the
> dominant costs are System.nanoTime() and a single cache line invalidation)
> and total memory footprint (~OS page size in bytes).
> A proper CLI command activates a sampler to collect (ie CSV) the profiled
> data, showing the precision of the sampling: data loss is not considered a
> failure condition.
