1) Because the typical use-case is passing file descriptors between different processes. 2) Because passing file descriptors implies a conversion step (that happens in the kernel), and a unit test that only uses two threads doesn't exercise this essential part of the functionality: If the conversion step was missing, the test wouldn't notice.
