I take one third of that back.  Based on the patched rsync 2.5.5, it
looks like the filesystem exposes the resource fork of a file F as a
file at the path "F/rsrc".  To perform a getxattr(F,
"com.apple.ResourceFork"), rsync will have to open and read "F/rsrc",
not call getattrlist.  (Supposedly the "F/rsrc" syntax is deprecated,
but rsync will only use it in Mac OS 10.3 and earlier, so we don't
care.)
