Per-task monitors use task_mon_slot to determine which slot in the array
to use for the monitor. During destruction, this slot is returned but
this is done before resetting the monitor. As a result, the monitor's
reset is in fact resetting a slot that is outside of the array
(RV_PER_TASK_MONITOR_INIT).
Release the slot only after the reset to avoid out-of-bound memory
access.
