In FUSE, is there a way to direct read() and write() operations directly
to a local file, without bouncing up to user space?    That's what the Coda
kernel module does today, and we need to think through the performance
implications if that is not possible.   The latency and bandwidth of
read() and write() operations are not slowed down by Venus today --- only
open() and close().   Will we be giving that up?   If we have to, will it matter?
