Log message:
Fix poll() busy-loop on socket close with POLLOUT
https://codereview.qt-project.org/c/qt/qtbase/+/651677
"On FreeBSD when asked for POLLOUT the poll() syscall returns only POLLHUP to
signify the fact that the other side closed the connection. It never sends
POLLERR for EOF cases, which results in a busy-loop inside the Glib dispatcher:
- poll() returns immediately with POLLHUP for a closed socket
- socketNotifierSourceCheck() does not detect it, because
events = POLLOUT | POLLERR and we get .revents = POLLHUP.
The (events & revents != 0) condition evaluates to false
- the code decides there is nothing to do and a new iteration starts"
