Hi Zhengyu,

close() works in BatchMode - at least for me (using the daily build,  
ImageJ 1.45e11).
E.g., there is no increase of memory usage with this:

nImg=1000;
setBatchMode(true);
for (i=0; i<nImg; i++) {
newImage("Untitled", "16-bit White", 2048, 2048, 1);
run("Invert");
showProgress(i/nImg);
close();
}
showProgress(1.0);
setBatchMode("exit and display");
