Thanks for checking.  Marking accordingly.

I wonder how this should be dealt with wrt squeeze.  Would it be okay
to apply the alignment fix on platforms with slow unaligned access in
a stable update, or is it okay to say "if you want to use iotop on
such platforms, you will need to install it from
backports.debian.org"?
