The current block tap code allows arbitrary numbers of image files to
be exported directly to domains without loopback.  I haven't done any
performance comparison to using loopback, but it might be useful if
people are mounting loads of images.  If it's something that people
would use, I could certainly clean it up over the next few weeks.
