Comment 1 for bug 1211417

I'm seeing this locally on my mako as well, with the 20130812 image. Strace has these messages being repeated very rapidly in a loop:
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=5, events=POLLIN}], 3, 6798485) = 1 ([{fd=3, revents=POLLNVAL}])
clock_gettime(CLOCK_MONOTONIC, {7622, 516167266}) = 0
clock_gettime(CLOCK_MONOTONIC, {7622, 516380909}) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=5, events=POLLIN}], 3, 6798484) = 1 ([{fd=3, revents=POLLNVAL}])
clock_gettime(CLOCK_MONOTONIC, {7622, 516869234}) = 0
clock_gettime(CLOCK_MONOTONIC, {7622, 517082877}) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=5, events=POLLIN}], 3, 6798483) = 1 ([{fd=3, revents=POLLNVAL}])
clock_gettime(CLOCK_MONOTONIC, {7622, 517571203}) = 0
clock_gettime(CLOCK_MONOTONIC, {7622, 517754325}) = 0
