+ * transfered by then) used in the speed computation, to be used instead of the
+ * start of the transfer.
+ * This starting point is regularly moved as transfer goes on, to keep getting
+ * accurate values (instead of average over the entire tranfer).
+ *
+ * This function takes the current amount of data transfered, the amount at the
+ * starting point, the limit (in bytes/s), the time of the starting point and
+ * the current time.
+ *
+ * Returns -1 if no waiting is needed (not enough data transfered since
+ * starting point yet), 0 when no waiting is needed but the starting point
+ * should be reset (to current), or the number of milliseconds to wait to get
+ * back under the speed limit.
