This is needed for Send/Recieve to correctly handle borders between the messages. The framing uses a single 32bit uint32 length for each frame, of which the high bit is used to indicate whether the message contains a file descriptor or not. This is enough to separate out each message sent and to decide to which message each file descriptors belongs, even though multiple Sends may be coalesced into a single read, and/or one Send can be split into multiple writes.
