//! Partial port of `OpenBSDMachine.c` — the OpenBSD per-host `Machine`.
//!
//! Ported here (operate on the base [`Machine`], so no unported substrate
//! is needed):
//! - `Machine_getCPUPhysicalCoreID` (`OpenBSDMachine.c:296`)
//! - `Machine_getCPUThreadIndex` (`OpenBSDMachine.c:302`)
//!
//! Still `todo!()` and blocked on unported substrate:
//! - `Machine_isCPUonline` reads `OpenBSDMachine.cpuData[id + 1].online`, so
//!   it needs the `OpenBSDMachine` struct modeled.
//! - the `OpenBSDMachine` struct plus `OpenBSDMachine_updateCPUcount` /
//!   `_scanMemoryInfo` / `_scanCPUTime` / `getKernelCPUTimes` /
//!   `kernelCPUTimesToHtop` need the `hw.ncpu`/`kern.cp_time2` sysctl scan.
//! - `Machine_scan` / `Machine_new` / `Machine_delete` additionally need
//!   `Machine_init` / `Machine_done` (still stubs in `machine.rs`) and
//!   `kvm_openfiles`/`kvm_close` FFI.
