    I am using it... 
    
    I just don't understand why you would only use the last callback.. why so 
much complexity added?
    
    
    if this complexity was added around say.. for instance... JournalImpl::show 
statistics.. I would go for it... but here at the sync calculation? I think 
this is being a lot of complexity for something that is supposed to be simple.


> HdrHistogram support on verbose SyncCalculation

> The SyncCalculation::syncTest could benefit of 
> [HdrHistogram|http://hdrhistogram.org/] support to represent the write 
> latencies percentile distribution while using it as a CLI command (ie through 
> the perf-journal command).
