Comment (by Baughn):
If setting FD_CLOEXEC (close on exec) is picked, then.. since it has to be
set in a separate call after opening the FD, there is a potential race
condition if any other thread calls exec. Probably only one OS thread
should do I/O or forks - my understanding is that this is already the
case, but it had to be mentioned.
