Measure the time an async I/O event has spent in the io_service completion event queue

I am wondering if there is a way to measure the time an async I/O event such as async_read or async_write spent in the io_service completion event queue before its completion handler got called.



The problem here is that you can't really timestamp the time when the event was inserted in the io_service queue which is something you can do when you post work to the io_service yourself - boost::asio::io_service occupied queue lengths for timers and posts



The idea is to check if an event has stayed in a ready state for too long. Then, you can eventually react on this and dynamically increase the worker threads.
