Events from each \fIinput\fR are queued by a
.c handShakeQ
galaxy.  A tree of
.c Arbitrate
stars provides fair arbitration where each \fIinput\fR has equal priority.
The data from the
.c handShakeQ
which receives control is passed to \fIdataOut\fR.  The response received by
\fIackIn\fR is routed through the waiting
.c handShakeQ
to the appropriate \fIoutput\fR.
