I regard this a bug in the definition of 2*big. I'm not sure
how many old documents will break if it is fixed, though. The
correct definition is:

  \defineblankmethod
      [2*big]
      {\addblankskip+{\bigskipamount}{\openlineheight}%
       \addblankskip+{\bigskipamount}{\openlineheight}}

The current definition is:

  \defineblankmethod
      [2*big]
      {\addblankskip+{2\bigskipamount}{2\openlineheight}}%

but that does not copy the stretch and shrink parts.

TeX is a bit stupid come to skip assignments, after

   \skip0=5pt plus 10pt minus 10pt
   \skip1=2\skip0

\skip0 will be *exactly* 10pt, without any glue components.

Cheers, Taco
