test3 DVD ISO not a multiple of 32KiB blocks

[James Ralston <qralston+ml redhat-fedora-test andrew cmu edu>]

FC2-test2-i386-DVD.iso was 4306010112 bytes, which is a multiple of
32KiB (specifically, 4306010112 bytes = 131409 32KiB-sized blocks).

However, FC2-test3-i386-DVD.iso is 4379752448 bytes, which is *not* a
multiple of 32KiB:

    $ factor 4379752448
    4379752448: 2 2 2 2 2 2 2 2 2 2 2 2138551

Therefore, growisofs pads it by 18432 bytes up to 4379770880 bytes
(133660 32KiB-sized blocks) when burning it.  This makes it a pain to
verify the MD5 checksums; instead of being able to just run md5sum on
the device (e.g., "md5sum /dev/hdc"), you have to use dd to read only
the size of the ISO (without the pad).

Was FC2-test3-i386-DVD.iso not being a multiple of 32KiB blocks in
size intentional, or just an oversight?  And will the DVD ISO for FC2
final be a multiple of 32KiB blocks in length?
