The infinite + loop this caused is now avoided by checking if the expected context is + already set before trying to fix it. + - Issue #20311: select.epoll.poll() now rounds the timeout away from zero, instead of rounding towards zero. For example, a timeout of one microsecond is now rounded to one millisecond, instead of being rounded to zero. |
