Well, we are both right!  It turns out the label table expansion size
had been changed in 5.0 from .75 MB to 3 MB.  The attached example
from my system shows a mixture of .75 MB and 3 MB label table extents.
 
The concept remains the same. When label table expands, it need exactly
.75MB or 3MB; otherwise, the expansion fails.  In addition, label table
can have multiple extent blocks (maximum 15 blocks or 300 extents to be
exact).
