So the current thread-based async dma patch is really just the wrong long

I see. So in other words:
don't ask for simple async I/O now. The more complex and flexible
sollution will follow soon.
Yes, hopefully really soon.
So i will wait patiently :-)
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?
I am working on an implementation and the first version will use the
posix aio and possibly the Windows ReadFile/WriteFile overlapped I/Os.
Anthony Liguori got a pre version of the code, but it is not commitable yet.
Fabrice.
