Actually upon consideration of the shape of the curve I went with
VARBINARY(80).  I'll be surprised if I ever see an LStat with length 75.


What is Job.PriorJob used for?  I have 486 rows currently in Job; in 480
of them, including the 68 rows in which PriorJobId is non-zero, PriorJob
is NULL, while in the remaining six rows it is an empty string.  Is it
even used?

It also appears in JobHisto, which has 338 rows, in all of which
PriorJob is NULL and PriorJobId is 0.
