PyObjC - API Notes for FSEvents API

The FSEvents package contains wrappers for the FSEvents API's, which are part of Carbon and not a standalone framework.

The FSEventsRef type is an opaque pointer, unlike what the name suggests this is not a CoreFounation based types. As a side-effect of that the programmer is responsibly for managing the retain-count of objects of this type.

This means you have to call FSEventStreamRelease when you're done with a stream. You must not use the stream after that, it will then refer to an invalid stream.
