Why does 0.0001pt make such a big difference?

Why does 0.0001pt make such a big difference?

[Peter Münster]

Hi,

Please compare \setupwhitespace[0.0001pt plus 2ex] with
\setupwhitespace[0pt plus 2ex] here:

\showframe
\setuphead[section][style={\switchtobodyfont[72pt]}]
\setupalign[height]
\setupwhitespace[0.0001pt plus 2ex]  % desired result
%\setupwhitespace[0pt plus 2ex]      % "plus 2ex" is unused
\starttext
\dorecurse{5}{\dorecurse{150}{bla }\par}
\section{test}
bla
\stoptext

Why is there such a difference please?

TIA,
-- 
           Peter

because the zero glue is discarded (in context) due to another one 
taking precedence; i'll be a bit more tolerant but i'm not sure of side 
effects

(for now using 1sp plus 2ex is quite ok)
