Hi Ingo,

I made a change on "perf bench" and made patch series
for parallel oriented benchmarking.

Previous perf bench provided only least
framework for each benchmark programs,
but I felt this was not enough.

Because it seems that lots of today's performance issue
is found by multi thread/process programs.

So I made perf bench to provide the framework
for easy parallel benchmark writing.

And this is a preparation for "perf bench syscall".
Because each benchmarks of system call
will be required parallel workloads,
but parallel frameworks for each benchmarks will be fat code.

Request for comments!
