The example of async I/O in Node.js is with a filesystem operation.
How does that work? AFAIK Linux, unlike windows, doesn't have a proper async API for filesystem I/O.
POSIX AIO is implemented using threads in libc and Linux AIO (io_submit, etc) only works with O_DIRECT (no kernel caching) and there are other issues depending on underlying filesystem driver.

Is there any solution?
