+// packeted_bio_create creates a filter BIO for testing protocols which expect
+// datagram BIOs. It implements a reliable datagram socket and reads and writes
+// packets by prefixing each packet with a big-endian 32-bit length. It must be
+// layered over a reliable blocking stream BIO.
+//
+// Note: packeted_bio_create exists because a SOCK_DGRAM socketpair on OS X is
+// does not block the caller, unlike on Linux. Writes simply fail with
+// ENOBUFS. POSIX also does not guarantee that such sockets are reliable.
