This appears to be causing the BSD bots to lock up when looking at the core dumps I've managed to get. Dropping the `FileDesc` structure triggers the `Arc` it's contained in to get cleaned up, invoking free(). This instead just closes the file descriptor (the arc itself is never cleaned up). I'm still not entirely sure why this is a problem because the pthreads runtime should register hooks for fork() to prevent this sort of deadlock, but perhaps that's only done on linux?
