    Handles polling and breaks down large buffers.
    2009-03-11  David Smith  <dsmith@redhat.com>
    
            * print_new.c (stp_print_flush): Breaks up the buffer into smaller
            pieces (since the ring_buffer likes lots of small events, not one
            large one).
            * transport/ring_buffer.c (__stp_alloc_ring_buffer): Reserves
            space for struct _stp_entry.
            (_stp_data_poll_trace): New function.
            (_stp_data_write_commit): Wakes up any tasks waiting on data.
