Don't know. My gut feeling is that we will end up with a
global credit algorithm pretty soon. I think the aio module
is too low-level for this, we should just spawn threads as
more aio requests come in. For smb1 I am not too worried
that we get overflowed, but with smb2 the picture might
change. But there we have the credit algorithm to slow down
clients when we get overflowed. I have no clue yet how this
might work, but I think that is the right place to tackle
the problem of getting flooded.
