POSIX2008 demands that `stat` contains an `st_mtim` field of type `timespec`. That field holds modification time with a nanosecond resolution. VxWorks reports _POSIX_VERSION as 200112. The `stat` struct does not contain `st_mtim`, but rather an `st_mtime` which holds a `time_t` which contains seconds. Because of that, when the test creates and modifies a file within one second, the polling watcher does not detect any changes. Fix the problem by postponing the watcher by 1s.
