What is the best way to center a table and control/fix the textwidth of the local footnotes?

I currently have:

\starttext

\startbuffer[Tab01]
\startlocalfootnotes
\bTABLE
\bTR\bTD So\eTD\bTD what%
\footnote{\input knuth} % <=
\eTD\eTR
\eTABLE
{\placelocalfootnotes}
\stoplocalfootnotes
\stopbuffer

\startplacetable[title=Test,
align=middle]
                  {\getbuffer[Tab01]}
\stopplacetable

\stoptext

If the footnote is commented out, the table is centered (as I want it). With the footnote, the table is flushleft. I have managed to get what I need by defining the \hsize of the footnotes and tweaking the loffset of the table. But a general, less “empirical” approach would be vastly better.
