self.send_async(self.censor(line) for line in open(path, 'r'))
or
self.send_async(map(self.censor, open(path, 'r')))
This is *not worse* than your first example
self.send_async(open(path, 'r'))
How do you write a managed uncensored variant? You can use the wrapper suggested by Mathias Panzenböck.
self.send_async(managed(open(path, 'r')))
self.send_async(self.censor(line) for line in managed(open(path, 'r')))
It is easy, clear, universal and requires no changes to syntax.
