We would continue the for - loop 

        // RSS values we get are sometimes somewhat delayed or inaccurate
        for (int iter=0; iter < maxIter; iter++) {

in this case, without a SkippedException.  In the original test before this change, we did not throw a SkippedException as well .
On the other hand , if we really run into the else - branch  we must have got a small   hostAvailableMemory value, so skipping the test might be a good idea because most likely the hostAvailableMemory  will not grow in the for loop,
