To simplify lifetime management of "listening" UDP sockets, UDP flow support needs to duplicate existing bound sockets. Those duplicates will be close()d when their corresponding flow expires, but we expect the original to still receive datagrams as always. That is, we expect the close() on the duplicate to remove the duplicated fd, but not to close the underlying UDP socket. Add a test program to doc/platform-requirements to verify this requirement.

Platform Requirements ===================== TODO: document the various Linux specific features we currently require Test Programs ------------- In some places we rely on quite specific behaviour of sockets. Although Linux, at least, seems to behave as required, It's not always clear from the available documentation if this is required by POSIX or some other specification. To specifically document those expectations this directory has some test programs which explicitly check for the behaviour we need. When/if we attempt a port to a new platform, running these to check behaviour would be a good place to start.
