It looks to be a limitation of Excel - the number of hyperlinks in a workbook
cannot exceed 65534. I didn't find it in the spec but confirmed it empirically.
If your code inserts 65533 hyperlinks then the workbook is OK, if the number of
hyperlinks is greater or equal to 65534 then the workbook is unreadable. 

I guess Excel tracks the number of hyperlinks as unsigned short and when this
number rolls over the workbook becomes corrupted.
