Comment (by rjvbertin@…):

 Replying to [comment:1 cal@…]:
 > As you noticed, interrupting installation/uninstallation is dangerous,
 especially in versions of MacPorts that don't have signal handling yet.

 If that's the case, there should be an additional safety: backup the
 registry.db file before starting the (un)installation process (and remove
 it after successful completion). Unless the backup file already exists, in
 which case an error should be raised or confirmation requested from the
 user.
