(Note: The analogous issues in tshark's io,stat in bugs 1 and 2 below were
reported and fixed in Bug 6883.)

Bug #1:  The LOAD stat in the last row of the tshark output and last column of
the Wireshark dialog is incorrect because rpc.time is divided by the full
interval rather than limiting the interval to the capture duration. 

Bug #2:  Intervals at the end of capture for which there is no data are not
displayed. 

Bug #3: When LOAD is selected and the user clicks an interval that does not
contain a response, the first frame of the next interval with a response minus
one is displayed. If there are gaps with no responses, a completely irrelevant
frame is selected.
