"An AsynchronousFileChannel is associated with a thread pool to which tasks are submitted to handle I/O events and dispatch to completion handlers that consume the results of I/O operations on the channel." This part is close to 17 years old now (java 1.7, 2007). The NIO for files that came with 1.4 (20y+) was not async for files either. I wonder where the 'truly async' idea has come from as the docs are rather explicit about it.
