//! Partial port of `SolarisMachine.c` — the Solaris/illumos per-host
//! `Machine`.
//!
//! Ported here (operate on the base [`Machine`], so no unported substrate
//! is needed):
//! - `Machine_getCPUPhysicalCoreID` (`SolarisMachine.c:333`)
//! - `Machine_getCPUThreadIndex` (`SolarisMachine.c:339`)
//!
//! Still `todo!()` and blocked on unported substrate:
//! - `Machine_isCPUonline` reads `SolarisMachine.cpus[id + 1].online`, so it
//!   needs the `SolarisMachine` struct modeled.
//! - the `SolarisMachine` struct plus `SolarisMachine_updateCPUcount` /
//!   `_scanCPUTime` / `_scanMemoryInfo` / `_scanZfsArcstats` need `libkstat`
//!   (`kstat_*`) FFI and the ZFS ARC kstats modeled.
//! - `Machine_scan` / `Machine_new` / `Machine_delete` additionally need
//!   `Machine_init` / `Machine_done` (still stubs in `machine.rs`) and
//!   `kstat_open`/`kstat_close` FFI.
