So I was trying to make sense of this, and ran into one little thing that
jumped out at me:

Now, I'll readily admit that I could be overly confused by this function.
When the variables are named "x", "xx", "xc", "x_vb_p", "xblob", and "lxd",
it all starts to run together. But still...

How can that be right? lxd is __user, it doesn't seem right to be
dereferencing it directly...?
Thanks,
