fix histogram resolution and measure message typo
source level 1.8 in pom
use a latch to wait for last iteration in handler
use deferred observables, don't forget to subscribe
use finallyDo and doOnNext instead of doOnTerminate and doOnEach
doOnEach can notify also at completion of the flux, not doOnNext
better handling of logging when cas mismatch vs other errors
fix : ratio repeat was done at wrong level, do it in flatMap
on errors log the exception, not just (sometimes empty) message
