Sure, I even implemented it once. Didn't get any faster. At that point
I realised that my kernel didn't actually support async I/O, and the
glibc emulation sucks for anything other than network I/O, so I gave
up.

Maybe one of these days I should work out if my current system supports
it, and give it another go...

Have enough systems actually got to the point of actually supporting
async I/O that it's worth implementing?

Have a nice day,
