Right now the calculation of the timeout isn't changed at all while the
test methodology (and the output of course) is changed only if `--verbose` is
specified: it is always possible to "validate" the output (the output
percentiles) turning off `--verbose` to see if the timeout estimation is
changed/different.
AFAIK the initial journal tuning is performed without `--verbose` hence I'm
expecting that nothing will change from the original version.
The other improvements (without affecting the no `--verbose` logic) are
made to help the JIT to avoid OSR in order to get more reliable results when
benchmarking vs temporary filesystem/very high speed devices/no fsync involved.
