Thank you Henri.
Now consider this:
-------------------------------
\setuplayout[grid=both]
\setupquotation[before={\switchtobodyfont[9pt]}]
\starttext
\showgrid
\input knuth
\startlinecorrection[halfline]
\startquotation
   \input sapolsky
\stopquotation
\stoplinecorrection
\input knuth
$\displaystyle{\frac{1}{a + b}}$
\input knuth
\stoptext
-------------------------------
Now the text snaps to the grid after the quotation, but the tall
formula inside the text overlaps with the text lines.
The solution would be a grid configuration that gives the line
containing the formula two lines of height, putting that only line in
the middle and then snapping the following lines again to the grid
(still solving the alignment of quotations as in the grid=both case).
Is it possible?
I suppose that this is not what you want,
but perhaps it can give you some some idea
\setuplayout[grid=both]
\setupquotation[before={\switchtobodyfont[9pt]}]
\starttext
\showgrid
\input knuth
\startlinecorrection[halfline]
\startquotation
   \input sapolsky
\stopquotation
\stoplinecorrection
linecorrection is to be used only with boxed material (normally 
something framed)
...
\input knuth
\setbox0=\hbox{$\displaystyle{\frac{1}{a + b}}$}%
\ruledvbox to 1\lineheight{\hsize=\wd0\vrule width0pt height0pt
depth1\lineheight \vss\box0\vss}
\input knuth
\stoptext
