This simple extension provides two functions to pass and receive file descriptors across UNIX domain sockets, using the BSD-4.3+ sendmsg() and recvmsg() interfaces.
Direct bindings to sendmsg() and recvmsg() are not provided, as the API does not map nicely into Python.
Please note that this only supports BSD-4.3+ style file descriptor passing, and was only tested on Linux. Patches are welcomed!
