Last change on this file since f00b26d4 was f00b26d4, checked in by Thierry Delisle <tdelisle@…>, 16 months ago

Re-worked IO to use epoll and support multiple io_contexts per cluster.
Also redid how cluster options are handled.
Changed how iofwd calls are passed to support future features and io_contexts rework.
