MacPort's use of hardlinks actually hit up against this in the initial
implementation. Apple has greatly improved HFS+ hardlink support, though. IIRC
things were much better under 10.4 and the (small) remaining performance
problems were fixed for 10.5.
I think jkh even posted to the list asking for any test cases where hardlink
performance was bad to be filed as bugs so that they could be fixed (in the
pre-10.5 days)...
