1/* @ajax/mesh-samplers: meshd's two sampler threads.
2 *
3 * - load (load.rs `sampler`): every second, this machine's host sample and
4 *   every loaded program's (mesh-load-host, mesh-load-prog) into the host
5 *   block's load regions and the mailbox's LOAD_PAGE; in a fleet, the member
6 *   summary to every member (F_LOADREP) and the scheduler's report (F_PERF,
7 *   through the fleet's hook).
8 * - net (net.rs `sampler`): every second, the interfaces that carry (or
9 *   carried) a peer link, and the total, into the host block's NIC records.
10 *
11 * Both run until sh->quit; a host that cannot be read is said once per
12 * distinct error, and the sample's age shows it to viewers. */
