You don't get to use LONELYMESSAGE for anything.  Intuition sets this
class for any message that had, at one time, been sent to somebody's
IDCMP port and has been replied back to Intuition.  As things are
happening, Intuition dynamically allocates its event message packets.
Before it goes and allocates another one, it looks to see if its
own reply port has any previously created messages that it can
possibly reuse.  I don't recall exactly what the source code does,
since I no longer have access to it, but if I remember correctly,
the class is set to LONELYMESSAGE if it is not doing involved with
carrying anything useful.  It is simply part of Intuition's high-water
mark of previously allocated, but currently unused, message blocks
that are to be reused before any other allocations take place.

Probably should have been specified in "include/8^)/intuinternals.h",
instead of a published file.
