As mentioned in this article, these classes are a work in progress.
Accordingly, we know of limitations in the classes that should not
be in place in the final versions.  We recommend that you use these
classes for informational purposes only.  They are not ready for
public consumption.  They will become available in a more finalized
form at the BeDC: Programming with the Media Kit on April 10, 1999.

The first thing to notice is the addition of the rt_alloc folder.
This contains headers and a source file for allocating into locked
memory.  This is needed to make sure that memory used for the node
does not get swapped out (and potentially have several milliseconds
worth of latency waiting for virtual memory.  The BTimedEventQueue
needs this functionality for its rt_map it uses for storage. Jon Watte
will be covering these issues in an upcoming newsletter article.
In the meantime, please do not use this functionality outside of this
class.
