Hi,
recent 'gsasl.c' uses poll(2) with
| pfd[1].events = POLLIN | POLLOUT;
The POLLOUT is triggered nearly everytime causing a very high CPU load:
| $ strace -t -p 22005
| 02:08:51 poll([{fd=0, events=POLLIN}, {fd=3, events=POLLIN|POLLOUT,
revents=POLLOUT}], 2, -1) = 1
| 02:08:51 poll([{fd=0, events=POLLIN}, {fd=3, events=POLLIN|POLLOUT,
revents=POLLOUT}], 2, -1) = 1
| 02:08:51 poll([{fd=0, events=POLLIN}, {fd=3, events=POLLIN|POLLOUT,
revents=POLLOUT}], 2, -1) = 1
| 02:08:51 poll([{fd=0, events=POLLIN}, {fd=3, events=POLLIN|POLLOUT,
revents=POLLOUT}], 2, -1) = 1
