* This routine attempts to delete a directory that may contain some files
* that are still in use. This latter point is only an issue on Windows and
* a few other systems.
*
* If the moveToTrash parameter is true we first rename the given directory
* "foo.Trash123" (where "foo" is the original directory name, and "123" is
* a random number, in order to support multiple concurrent deletes). The
* directory is then deleted, file-by-file, on a background thread.
*
* If the moveToTrash parameter is false, then the given directory is deleted
* directly.
*
* If 'delay' is non-zero, the directory will not be deleted until the
* specified number of milliseconds have passed. (The directory is still
* renamed immediately if 'moveToTrash' is passed, so upon return it is safe
* to create a directory with the same name).
