yes, i see it. the interlineskip with line=7pt is bigger than the one
with line=8pt.

i looked for the definition of \lineskiplimit at

http://www.tug.org/utilities/plain/cseq.html#lineskiplimit-rp

[..]
IF the glue specified by \baselineskip brings two adjacent boxes in a
vertical list closer together than \lineskiplimit, then \lineskip glue
is placed between the boxes [78].

\def\checkgridsnapping
  {\lineskip\ifgridsnapping\zeropoint\else\normallineskip\fi}

so setting this value while using grid make not much sense. took me some
time (also grid beginner), but i guess the attached example is a
starting point. oh, and thanks to Wolfgang for his much nicer code
(assimilated).
