Switched to using posted next events after sendfile_max_chunk. Previously, 1 millisecond delay was used instead. In certain edge cases this might result in noticeable performance degradation though, notably on Linux with typical CONFIG_HZ=250 (so 1ms delay becomes 4ms), sendfile_max_chunk 2m, and link speed above 2.5 Gbps. Using posted next events removes the artificial delay and makes processing fast in all cases.
