- * The AFS async daemon is used to the following:
- * - probe "dead" servers to see whether they've come back to life yet.
- * - probe "live" servers that we haven't talked to for a while to see if they are better
- *   candidates for serving than what we're currently using
- * - poll volume location servers to keep up to date volume location lists
