Actually this happens with plain poll() as well, at least on Linux:

poll([{fd=3, events=POLLIN}, {fd=10, events=POLLIN}, {fd=11,
events=POLLIN}, {fd=12, events=POLLIN}, {fd=15, events=0}, {fd=16,
events=0}], 6, 1000) = 2 ([{fd=15, revents=POLLHUP}, {fd=16,
revents=POLLHUP}])
poll([{fd=3, events=POLLIN}, {fd=10, events=POLLIN}, {fd=11,
events=POLLIN}, {fd=12, events=POLLIN}, {fd=15, events=0}, {fd=16,
events=0}], 6, 1000) = 2 ([{fd=15, revents=POLLHUP}, {fd=16,
revents=POLLHUP}])
poll([{fd=3, events=POLLIN}, {fd=10, events=POLLIN}, {fd=11,
events=POLLIN}, {fd=12, events=POLLIN}, {fd=15, events=0}, {fd=16,
events=0}], 6, 1000) = 2 ([{fd=15, revents=POLLHUP}, {fd=16,
revents=POLLHUP}])
poll([{fd=3, events=POLLIN}, {fd=10, events=POLLIN}, {fd=11,
events=POLLIN}, {fd=12, events=POLLIN}, {fd=15, events=0}, {fd=16,
events=0}], 6, 1000) = 2 ([{fd=15, revents=POLLHUP}, {fd=16,
revents=POLLHUP}])
