+# It's quite possible that the user might specify the same source file
+# more than once on the command line, perhaps through shell variables
+# or wildcard expansions.  It might cause problems for rsync if the
+# same name occurred more than once in the file list, because we might
+# be trying to update the first copy and generate checksums for the
+# second copy at the same time.  See clean_flist() for the implementation.
+
+# We don't need to worry about hardlinks or symlinks.  Because we
+# always rename-and-replace the new copy, they can't affect us.
+
+# This test is not great, because it is a timing-dependent bug.
