+  Removes orphaned job keys that exist in Redis but are not referenced

+    ARGV[1]  number of state key suffixes
+    ARGV[2 .. 1+N]  state key suffixes (e.g. active, wait, completed, ...)

+    ARGV[3+N .. 2+N+M]  job sub-key suffixes (e.g. logs, dependencies, ...)
+    ARGV[3+N+M .. end]  candidate job IDs to check
