Might be more effort than it is worth but any thoughts on userland error 
handling for passthrough? My use case, optionally, responds to read or 
write errors in particular ways. It's not an unreasonable tradeoff to 
disable passthrough if the user wants those features but was wondering 
if there was any consideration of extending the protocol to pass 
read/write errors back to the fuse server.
