I don't think it was user error, just a hard to track down bug.
Actually my guess is that lxc (bc you just did sleep 10) wasn't
pinning the fs, but something resulting from debootstrap was.  In
the past I've seen udev tasks be started which kept me from deleting
lvm partitions with containers on them.
