Why not just set the FD to -1?
It'll give bad a EBADF instead of ENOTCONNECTED (or whatever),
but it seems better...  no flags, i guess it's "racy" but that's
intrinsic to the circumstance of having one thread writing and another closing.
(Really, the caller is going to have to have a lock if they want
multiple threads to write to the same fd)
