I have to make some additions to this. In principle, everything works well, 
so no problem with texexec due to updates. But there are problems with more 
complex MP code, possibly with metaobj. My test file:

\startreusableMPgraphic{nometaobj}
    draw unitsquare scaled 1cm;
\stopreusableMPgraphic

\startreusableMPgraphic{justinput}
    input metaobj;
    draw unitsquare scaled 1cm;
\stopreusableMPgraphic

\startreusableMPgraphic{metaobj}
    input metaobj;
    newBox.testbox(btex Where is it? etex);
    testbox.c=origin;
    drawObj(testbox);
\stopreusableMPgraphic

\starttext
    \reuseMPgraphic{...}
\stoptext

witth {...}={nometaobj} as well as {...}={justinput}, everything works 
fine. But with {...}={metaobj}, I get the nearly empty log above. Compiling 
via mp mpgraph works. So, this might be some interference with metaobj, or 
perhaps a general problem with complex MP code (but I can't imagine this 
looking at the available examples...)
And as I wrote before, with runtime mp via \write18, all three test 
graphics work.
