Just for kicks, rewrite the GetThreadContext call as this and see if it works 
in 2.053:

            for( int i = 0; !GetThreadContext( t.m_hndl, &context ); i++ )
            {
                if( i > 99 )
                    throw new ThreadException( "Unable to load thread context" 
);
                Thread.yield();
            }
