That may be the case, although I'm not sure that this is really the case
for a system such as a database engine, which manages its IO completely,
and doesn't want the OS to interfere in any way (and wants to use kernel
async IO if it's available).

In any case I don't have control over the source of the app, so there's
no way for me to tell the program to use the O_DIRECT flag...
