+# This outputs 6 columns:
+# PID FD BLOCKED_TIME RESCHEDULE_TIME METHOD PATH
+#
+# PID - pid of cmogstored process
+# FD - descriptor of client
+# BLOCKED_TIME - total time a client spent blocked
+# RESCHEDULE_TIME - the time a client went from unblocked to dispatching
+# METHOD - HTTP or sidechannel method (e.g. GET/HEAD/PUT/DELETE/MD5)
+# PATH - path accessed (e.g. /dev666/usage)
+#
+# [PID,FD] - unique identifier on any host at that point-in-time
+# BLOCKED_TIME - RESCHEDULE_TIME = time actually spent in the queue
+# RESCHEDULE_TIME is usually very low.
