Why?  As a matter of fact that was the primary reason I even started
with this patchset: that Gc.compact was sitting in the middle of the
main v2v function and was yet another obstacle in the refactoring I was
after.

Now that the extra guestfs handle doesn't survive beyond
copy_virtio_drivers() what is the need for that explicit GC (which was
introduced at the time exactly to clear up that handle in commit
47b5f245bec908f803f0a89c3b1e3166cfe33aad)?
