bup-tick - wait for up to one second
bup tick waits until time(2) returns a different value than it originally did. Since time() has a granularity of one second, this can cause a delay of up to one second. This program is useful for writing tests that need to ensure a file date will be seen as modified. It is slightly better than sleep(1) since it sometimes waits for less than one second.
