AI Summary: The GitHub issue identifies an inefficiency in a coroutine-based asynchronous I/O read operation. Currently, a coroutine suspends immediately after submitting a read request to the kernel, only processing the previously read data upon resumption. The proposed optimization is to allow the coroutine to process the data from the *previous* read *concurrently* while the kernel is handling the *current* read request, before suspending, which can be achieved using a double-buffering strategy.
