Wait to make the test system correctly recognize the 'bar' file as
touched after the next build run. Without the wait, the next build run may
rebuild the 'bar' file with the new and the old file modification timestamp
too close to each other - which could, depending on the currently supported
file modification timestamp resolution, be detected as 'no change' by the
testing system.
