| // 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. |
