it was a fairly complex scenario,
involving source files > 64K
and some extraordinary conditions related to specific layout of ranges of zeroes.

ensure bench speed measurement is more accurate for small inputs
...
Previous method would produce too many time() invocations,
becoming a significant fraction of workload measured.
The new strategy is to use time() only once per batch,
and dynamically resize batch size so that each round lasts approximately 1 second.
This only matters for small inputs.
Measurement for large files (such as silesia.tar) are much less impacted
(though decoding speed is so fast that even medium-size files will notice an improvement).

[bench] Use higher resolution timer on POSIX
...
The timer used was only accurate up to 0.01 seconds. This timer is accurate up to 1 ns.
It is a monotonic timer that measures the real time difference, not on CPU time.
