+1. I fail to understand why anyone would think it's a good idea for us
to build our own I/O stack. The resources that would be consumed by that
would probably be enough to sink the project, or at least ensure that we
made no progress on any other aspect of the system for a good long time.
(And I'm just talking development, never mind maintenance.)
Far better to invest some effort in providing decent feedback to the
platforms we depend on.
