Sebastien,

These results look great.   I should say we also have patches to add
native libAIO support to MySQL/Innodb.  It would be interesting to
benchmark against.  Would you be interested in it ?

Also about your library - do you think it will become the standard part
of Linux distributions some time in the future ? 

Would you be willing to contribute the patches you developed to be part
of standard MySQL distribution ? 

Are patches expected to work on other Unix versions if they have POSIX
AIO implementation ?
