It seems to do what I wanted. Putting small figures in the margin on  
the next page from where the call is made.

I seem to remember some mentioning of remaining space on the page in  
"ConTeXt-fashion" but cannot find it again.
Or can I just rely on TeX's \pagetotal? I tried something as:
	\scratchdimen=\textheight
	\advance\scratchdimen by -\pagetotal
	\ifdim\scratchdimen<#1\relax .......

Is it an option to enrich \startpostponing to \startpostponing 
[need=distance]?
( reprogramming \setvalue{\e!start\v!postponing} is it?  asks a bit  
too much of my inner-ConTeXt skills)

I tried something on the following lines, but got stuck with a  
remaining \stoppostponing when there appears to enough space.
Defining \stoppostponing to \empty seems not to work.
	\def\startpostponingwhen[#1]{%
	\scratchdimen=\textheight
	\advance\scratchdimen by -\pagetotal
	\ifdim\scratchdimen<#1\relax
		\let\dostoppostponingwhen=\stoppostponing
		\expandafter\startpostponing
	\fi}
