//
// This interface works a bit differently from the other proc_info(3) flavors.
// It copies out a structure with a variable-length array at the end of it.
// The start of the `proc_threadcounts` structure contains a header indicating
// the length of the subsequent array of `proc_threadcounts_data` elements.

// sizeof(proc_threadcounts) + nperflevels * sizeof(proc_threadcounts_data)
//
// Use the `hw.perflevel[0-9].name` sysctl to find out which perf-level maps to
// each entry in the array.
