However, PA has a point that while the coroutines are
properly multi-plexed in terms of socket io, the other
IOs are not. Say for example, if I have a SQL related
begin tran/end tran, it would be blocked and the whole
thing stop until I get out of this blocking IO. And in
a sense, the high performance design has been
serialized by this link.
