[daip] VBGLU bug

[Eric Greisen]

Okay I think I got it.  Attached is a corrected version.  Your 2nd
data set had significant sections of data where the first data set had
none.  This triggered an error in the code.

I noticed that the table handling went very fast - did you delete
tables or has the problem mysteriously vanished.  Amy was starting to
look at the issue and this absence of times in data set 1 but found in
data set 2 occurred to her as a source of slowness.

I will send the code in the next message.
