Watching for what?

My code is really basic, when the directory modified timestamp
changes, I list the directory entries with `dirEntries` and
then call `dirEntry.getTimes()` on it.
The right way to implement a function which watches for changes
IN the directory is to use an appropriate notification API, e.g.
inotify [1]. No one wants software running on their computer
which runs in a loop and polls the file system endlessly though
there is no actual work to do.
```d
[...]
entry.getTimes(ac, st);
```
You know what symlinks [2] are? You want the timestamps of the
symlink and not that of the pointed-to file. In C you would use
`lstat` instead of `stat` for that purpose.
Sometimes symlinks are used to link to objects which are not
located in the filesystem [3]. Trying to use getTimes on such
object throws an exception.
