- * \ingroup block
+ * \ingroup misc_blk
  *
  * input: one stream of itemsize; output: one stream of itemsize
+ *
+ * N.B. this should only be used in GUI apps where there is no other
+ * rate limiting block.  It is not intended nor effective at precisely
+ * controlling the rate of samples.  That should be controlled by a
+ * source or sink tied to sample clock.  E.g., a USRP or audio card.
