- * NEEDSWORK: these two are tricky. The callers assume there is a

- * read from the right place. And they do not know or care who called
- * by them uses the attribute subsystem, hence have no knowledge of
- * existing git_attr_check instances or future ones that will be
- * created).
- *
- * Probably we need a thread_local that holds these two variables,
- * and a list of git_attr_check instances (which need to be maintained
- * by hooking into git_attr_check_alloc(), git_attr_check_initl(), and
- * git_attr_check_clear(). Then git_attr_set_direction() updates the
- * fields in that thread_local for these two variables, iterate over
- * all the active git_attr_check instances and discard the attr_stack

+ * Callers into the attribute system assume there is a single, system-wide

+ * attribute system will lazily read from the right place. Since changing
+ * direction causes a global paradigm shift, it should not ever be called while
