/**
 * This routine attempts to delete a directory that may contain some files that
 * are still in use.  This later point is only an issue on Windows and a few
 * other systems.
 *
 * If the moveToTrash parameter is true, then the process for deleting the
 * directory creates a sibling directory of the same name with the ".Trash"
 * suffix.  It then attempts to move the given directory into the corresponding
 * trash folder (moving individual files if necessary).  Next, it proceeds to
 * delete each file in the trash folder on a low-priority background thread.
 *
 * If the moveToTrash parameter is false, then the given directory is deleted
 * directly.
 *
 * If the sync flag is true, then the delete operation runs to completion
 * before this function returns.  Otherwise, deletion occurs asynchronously.
 *
 * 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). This parameter is ignored if
 * 'sync' is true.
