I meant actually allowing performance critical pieces to work either
in-user or in-kernel.  How, I'm not sure ... if we could use the same
code for both, that would be brilliant ... if we have to have separate
pieces, that will be OK.

The error injection and transport debug people think it's important to
have the state machine in user space for fast prototyping and debugging,
so I'm not going to take this away from them.

Sounds like a plan.  (However, it also sounds suspiciously like the last
plan we had from the storage summit which didn't actually attract any
implementers ...)
