* If we get here, we have received a SIGHUP, which means to
* reread our configuration file.
+ *
+ * The algorithm used is as follows: we count how many jobs are
+ * running and mark the running jobs to make a callback on
+ * exiting. The old config is saved with the reload table
+ * id in a reload table. The new config file is read. Now, as
+ * each job exits, it calls back to the reload_job_end_cb(), which
+ * decrements the count of open jobs for the given reload table.
+ * When the count goes to zero, we release those resources.
+ * This allows us to have pointers into the resource table (from
+ * jobs), and once they exit and all the pointers are released, we
+ * release the old table. Note, if no new jobs are running since the
+ * last reload, then the old resources will be immediately release.
+ * A console is considered a job because it may have pointers to
+ * resources, but a SYSTEM job is not since it *should* not have any
+ * permanent pointers to jobs.
