In the same manner as the --prepare phase exists, the feature request is for a non-timed --conclude or --post phase that would run after each benchmarked command. There would each be 1 or N number of these.

In my use case, I cannot do the cleanup after the command executes W(armup)+N times. I also understand that running in this phase can pollute the cache, but in my case, the benchmarks can already run for hours.

The current workaround is to put the per command shutdown steps in each bechmarked command but that pollutes the benchmarking times.

Thanks again for an excellent utility
