This is the only solution I've come up with so far:
Create a shared/upgrade-libfoo-to-version-blah template, include it in every
package that relies on the foo library, and have them all ask the question in
.config and check it in .preinst. They will all have to Pre-Depend on debconf.
The installation run still breaks messily if other packages are being upgraded
at the same time.
I hate it. At this point, I am considering just displaying a note advising the
user to interrupt the installation themselves, as there is no good way to do it
programmatically, and the user has a good chance of being able to send a
keyboard interrupt before dpkg actually unpacks everything.
