Philip Susi: Confirmed with the Bionic live CD:

root@xubuntu:~# cat /proc/cmdline
BOOT_IMAGE=(loop)/casper/vmlinuz boot=casper iso-scan/filename=/linux/xubuntu-18.04-desktop-amd64.iso toram

root@xubuntu:~# umount /isodevice
umount: /isodevice: target is busy.

root@xubuntu:~# losetup -d /dev/loop0

root@xubuntu:~# umount /isodevice
(succeeds)

However, I did not observe the issue as originally reported; Ubiquity was able to install the system even with /isodevice mounted and unable to be unmounted. (In my case, the ISO file was on a USB thumbdrive, and I installed to a hard drive.)
