Description

The timing algorithm is basically broken, since Thread.sleep is imprecise. There is also a counter error in the looping code.

The following testcase will never run in less than 4 seconds on my machine

public void testRealWallTime()

{ long start = System.currentTimeMillis(); FileUtils.waitFor(new File(""), 2); System.out.println("elapsed = " + (System.currentTimeMillis() - start)); }
