The src/libstd/sys/unix/net.rs file depends on it. It is missing from Haiku. This workaround should actually 'fix' the problem, but it turns out the fds-are-cloexec.rs test hangs. I do not know how related these two issues are, but it warrants further investigation. The test is ignored on this platform for now. * Hand rebased from Niels original work on 1.9.0
