But it *is* exceptional behavior for the file read to fail.  The normal
behavior is for the call to succeed, right?

Exceptions are handy for all sorts of things.  One of my projects uses
something like:

    class Success(Exception):
        def __init__(self, added = 0, deleted = 0, modified = 0):
            self.added = added
            self.deleted = deleted
            self.modified = modified

to hold return values from various calls.  I use it like:

    try:
        SomeDatabaseQuery()
    except Success, result:
        print 'Just added %d new entries.' % result.added
    except:
        print 'The query failed.'

Don't limit yourself to a particular style simply because of the name.
