    I have tried to avod NIO swich as much as possible. My concern was a situation where e.g.
file privilegues would block access to the journal which would make AIO open to fail and than
fallback to NIO. But If you don't like it let me know I'll remove it.

AIO might still fail if the underlying FS does not support required features (direct async
I/O).
> Example filesystems on Linux: tmpfs, ZFS (using zfsonlinux driver).
