Why are you so keen on doing it wrong?

No, you are not safe. If the child process dies because of a
segmentation fault (or whatever), the parent will notice this through
the EOF received (I am assuming here, since you couldn't be bothered
with closing a file descriptor, that you did not install a SIGCHLD
handler to monitor for this possibility). This means that should one
process die unexpectedly, the other will hang forever.

Best practices are there for a reason, despite what others here might
have you think.
