On emacs-devel, Eli said:
AFAICT, this loop in deactivate_process:
/* Beware SIGCHLD hereabouts. */
for (i = 0; i < PROCESS_OPEN_FDS; i++)
close_process_fd (&p->open_fd[i]);
doesn't close the last of the 4 descriptors opened by the 2 emacs_pipe
calls in make-pipe-process. It calls 'close' with the right value,
and close returns zero, but the pipe stays open. In Emacs 28, this
same loop successfully closes the descriptor. I don't know why.
Perhaps bisecting could help.
