Can you have it not do hard-links on Mac?
Mac has hard-links, but the implementation is very poor. So it would be 
better if it didn't. Basically, for every file that has a hard-link, 
there is a directory entry in a specific directory. Which means if you 
have 100,000 hardlinked files scattered around your filesystem, there is 
a directory with 100k filenames. When I was working with bazaar, I found 
that keeping a revision library actually hurt performance, because of 
all the hard-links. (you obviously needed ++pristine-trees, but checking 
against a ++pristine-tree was faster than a revlib)

Also, is this hard-linking to --basis or to the branch being pulled from 
    (or is it just wherever it can get the file)?
