Copy filter: wake up subrequests after aio operations. Previously, connection write handler was called, resulting in wake up of the active subrequest. This change makes it possible to read data in non-active subrequests as well. For example, this allows SSI to process instructions in non-active subrequests earlier and start additional subrequests if needed, reducing overall response time.
