    Description

      The libprocess subprocess API accepts a set of whitelisted file descriptors that are supposed to be inherited to the child process. On windows, these are used, but otherwise the subprocess API just ignores them. We probably should make sure that the API clears the CLOEXEC flag on this descriptors so that they are inherited to the child.
