- The main-loop has been changed to process all ready IO sources with a
zero timeout in the same loop iteration. Previously, two zero-timeout
sources would require two main-loop iterations. Further, when the main-loop
is polling IO sources with file descriptors, zero timeout IO sources are
added to the list of sources to be processed as well.
The intervals to decide when FD based IO sources are checked for readiness
have been made configurable through ``io_poll_interval_default`` and
``io_poll_interval_live`` for ease of testing, development and debugging
of the main-loop.
