    I accept that steal time is worthwhile, but do you have some way to
    demonstrate that the implementation actually works and is beneficial?

    Perhaps run two cpu-bound compute processes on one vcpu, overcommit that
    vcpu, and see what happens to the processing rate with and without steal
    time accounting. I'd expect a fairer response with steal time accounting.

    error compiling committee.c: too many arguments to function
