I have this in some client code in an import script that removes all 
contents from a folder, before adding new contents (which are expected 
to be mostly the same):


from plone.app.linkintegrity.exceptions import \
     LinkIntegrityNotificationException

for oid in target_folder.contentIds():
     try:
         target_folder._delObject(oid)
     except LinkIntegrityNotificationException:
         # Despite the exception, this item has been removed
         # anyway...
         logger.warn("Possible link integrity problems for %s", oid)


It has been a while ago since I (or a colleague) wrote this code, but I 
think the idea is that without the try/except the exception would cause 
the transaction to be aborted (so the object would remain in the 
database) and would redirect to tje deletion confimation screen.  With 
the try/except in place the object stays deleted and no redirection 
takes place.
