Is anyone actively working on this, or is it just speculation? I'd
greatly prefer (and might do, if no one is working on it and Fabrice
would take it) do a libaio version, since that'll for sure perform the
best on Linux. But a posixaio version might be saner, as that should
work on other operating systems as well.
Fabrice, can you let people know what you would prefer?
