Comment (by nh2):

 Addition to above comment:

 Probably the only time that worked was before commit
 [https://github.com/ghc/ghc/commit/b0316cdb10fbd9eaca7ede28c7bb3eb19f7766bf
 b0316cdb] (#9169) that added the `FD_SETSIZE` check -- in which case it
 probably only worked due to writing to (and likely corrupting) out-of-
 bounds memory beyond the size of the `fd_set`.
