 Note that AnyEvent::Handle will automatically C<start_read> for you when
 you change the C<on_read> callback or push/unshift a read callback, and it
 will automatically C<stop_read> for you when neither C<on_read> is set nor
 there are any read requests in the queue.
-These methods will have no effect when in TLS mode (as TLS doesn't support
+In older versions of this module (<= 5.3), these methods had no effect,
-half-duplex connections).
+as TLS does not support half-duplex connections. In current versions they
+work as expected, as this behaviour is required to avoid certain resource
+attacks, where the program would be forced to read (and buffer) arbitrary
+amounts of data before being able to send some data. The drawback is that
+some readings of the the SSL/TLS specifications basically require this
+attack to be working, as SSL/TLS implementations might stall sending data
+during a rehandshake.
+As a guideline, during the initial handshake, you should not stop reading,
+and as a client, it might cause problems, depending on your applciation.
