My todo diff in the file (just reverted) was:

+#Problem:

As for extents, is this the same as sparse file support? Because you can either
have a sparse tarball or truncate -s. (Or truncate -s a file and then make a
tarball with --sparse and see if the first 512 bytes generated header is right...)

I'd du but... xattr stuff. :(
