nice is not applied, railsbench fails to bundle install #3

Hello,

I've been trying to run this and noticed that the generated command:

setarch x86_64 -R nice -20 taskset -c 11 ruby --yjit -I ./harness benchmarks/optcarrot/benchmark.rb

actually causes the process to have a nice level of 19, the least priority, when trying locally on Linux.

It seems one needs nice -n -40 (can be tested with nice -n -40 sleep 1000) to actually use a negative nice level, and that also needs sudo (otherwise: nice: cannot set niceness: Permission denied and it has no effect).

BTW, I also noticed run_benchmarks.rb uses 4 spaces as indentation which is quite unusual for Ruby. I'd make a PR for it, but it's probably best if you change it to avoid any conflict.

Finally, my run failed with:

$ ./run_benchmarks.rb
...
Running benchmark "railsbench" (12/13)
setarch x86_64 -R nice -20 taskset -c 11 ruby --yjit -I ./harness benchmarks/railsbench/benchmark.rb
Could not find concurrent-ruby-1.1.8 in any of the sources
Run `bundle install` to install missing gems.
./run_benchmarks.rb:13:in `check_call': RuntimeError (RuntimeError)
	from ./run_benchmarks.rb:220:in `block in run_benchmarks'
	from ./run_benchmarks.rb:188:in `each'
	from ./run_benchmarks.rb:188:in `each_with_index'
	from ./run_benchmarks.rb:188:in `run_benchmarks'
	from ./run_benchmarks.rb:282:in `<main>'
zsh: exit 1     ./run_benchmarks.rb

So I guess one should bundle install before in benchmarks/railsbench (either in README or by the harness).
bundle install currently fails though due to mimemagic 0.3.5 being yanked.
