    Fix Description: Add an "ElapsedTime" column to the -m/-M output.  This column
    is the cumulative etimes of all operations during that time period.

    Ticket #47349 - DS instance crashes under a high load

    Fix Description: handle_new_connection initializes the connection object,
    then calls connection_table_move_connection_on_to_active_list to put it
    on the list of active connections, then unlocks the c_mutex, then calls
    connection_new_private to allocate c_private.  If another thread
    interrupts after the conn has been moved to the active list, but before
    c_private has been allocated, the new conn will be available via
    connection_table_iterate_active_connections where table_iterate_function
    will attempt to dereference the NULL c_private.
    The fix is to move connection_new_private inside the c_mutex lock, and to
    move connection_table_move_connection_on_to_active_list to be the very last
    thing before releasing the c_mutex lock.  Once the conn is on the active
    list it is live and we cannot do anything else to it.
    Note: I have still not been able to reproduce the problem in a non-debug
    optimized build.
