[interfacekit] Re: BHandler::StartWatching()


A warning. The BeBook is somewhat incorrect on this topic. I can't
remember the exact details, but I know that how it works in R5 and how
it is documented in the BeBook differ.

If you want R5 compat, you will probably have to do some imperical
testing.

The story behind this feature is that it was 'snuck' in so it didn't get
as much testing and doc as it really should have.
