+// PacketedBioCreate creates a filter BIO which implements a reliable in-order
+// blocking datagram socket. The resulting BIO, on |BIO_read|, may simulate a
+// timeout which sets |*out_timeout| to the timeout and fails the read.
+// |*out_timeout| must be zero on entry to |BIO_read|; it is an error to not
+// apply the timeout before the next |BIO_read|.
+//
+// Note: The read timeout simulation is intended to be used with the async BIO
+// wrapper. It doesn't simulate BIO_CTRL_DGRAM_SET_NEXT_TIMEOUT, used in DTLS's
+// blocking mode.
