Ah, another example of italian typesetting:
\setuplayout[height=12cm]
\starttext
\xypos{b1}\input tufte\xypos{e1}
\doifpositionsonsamepageelse{e1,b2}{yes}{no}
\xypos{b2}\input tufte\xypos{e2}
\doifpositionsonsamepageelse{e2,b3}{yes}{no}
\xypos{b3}\input tufte\xypos{e3} \page
\doifpositionsonsamepageelse{e3,b4}{yes}{no}
\xypos{b4}\input tufte\xypos{e4}
\stoptext
Unfortunately i found out that there is a circular call in the macro (will
send you the patch)
[beware: such playing with spacing may influence the process and you can
end up in cycles, so, make sure to start without a tuo file, and only move
forward, not back]
