I have reproduced it and here's the strace output:
poll([{fd=0, events=0}, {fd=5, events=POLLIN|POLLHUP}, {fd=4, events=POLLOUT}], 3, -1) = 1 ([{fd=4, revents=POLLOUT}])
poll([{fd=0, events=0}, {fd=5, events=POLLIN|POLLHUP}, {fd=4, events=POLLOUT}], 3, -1) = 1 ([{fd=4, revents=POLLOUT}])
poll([{fd=0, events=0}, {fd=5, events=POLLIN|POLLHUP}, {fd=4, events=POLLOUT}], 3, -1) = 1 ([{fd=4, revents=POLLOUT}])
poll([{fd=0, events=0}, {fd=5, events=POLLIN|POLLHUP}, {fd=4, events=POLLOUT}], 3, -1) = 1 ([{fd=4, revents=POLLOUT}])
poll([{fd=0, events=0}, {fd=5, events=POLLIN|POLLHUP}, {fd=4, events=POLLOUT}], 3, -1) = 1 ([{fd=4, revents=POLLOUT}])
poll([{fd=0, events=0}, {fd=5, events=POLLIN|POLLHUP}, {fd=4, events=POLLOUT}], 3, -1) = 1 ([{fd=4, revents=POLLOUT}])
poll([{fd=0, events=0}, {fd=5, events=POLLIN|POLLHUP}, {fd=4, events=POLLOUT}], 3, -1) = 1 ([{fd=4, revents=POLLOUT}])
poll([{fd=0, events=0}, {fd=5, events=POLLIN|POLLHUP}, {fd=4, events=POLLOUT}], 3, -1) = 1 ([{fd=4, revents=POLLOUT}])
poll([{fd=0, events=0}, {fd=5, events=POLLIN|POLLHUP}, {fd=4, events=POLLOUT}], 3, -1) = 1 ([{fd=4, revents=POLLOUT}])
poll([{fd=0, events=0}, {fd=5, events=POLLIN|POLLHUP}, {fd=4, events=POLLOUT}], 3, -1) = 1 ([{fd=4, revents=POLLOUT}])
...
ad infinitum
