\definegridsnapping[crap] [fit,0.2]
\setuplayout[grid=crap]

but if you really need that kind of tweaks you might consider using a 
better font: if interlinespace is too small you will never get nice results

you can try to play with the h/d ratio:

\setupinterlinespace[line=2.8ex,height=0.8,depth=0.2]
\showstruts \strut x
\setupinterlinespace[line=2.8ex,height=0.7,depth=0.3]
\showstruts \strut x

or you can plug in a command (in the toc handler) that puts each line in 
a box with manipulated dimensions
