No argument here.  I didn't intend to imply that the two were the same in
this respect, just that they both represented cases where community
projects are not necessarily aligned with Sun's business needs.  Further,
it was 32-bit SPARC kernel support in particular that I was thinking of as
having potential "long-term impact" on Sun's resources.
