What would be "too many"? -- a few million?  I have files in a test
setup that have over 7000 files hard linked (only an 8 byte file, but since
minimum block size is 4K, that would be 28MB w/o the hard link v. 4k with.

It would NOT be good for rsync to start breaking
links w/standard options.  Maybe a new option
to allow link breaking?
