No, you must write to the pipe to detect it is broken. And you won't

I skim over that discussion (because I don't agree with the design) so
I can't make any substantial comments, but here's a nitpick: if you
use an asynchronous event loop, your selector triggers - POLLHUP for
poll(), not sure if it's writability or exception for select()- as
soon as a pipe is broken.
Hi Laurent.
My experience is select() doesn't ever give you anything from
exception, on Linux.
And fifosvd must close the write end of the pipe; therefore cannot
poll for writeability.
