Currently the server will not continue if it can't write to the log file, that
is the only file it actually needs to write to. I can add configuration
parameter if required to disable this. My thinking was that if you are running a
server against a database you really should be logging what its doing.

Let me know if you would like this option.

The reason that you get this cryptic message is that the server has already
exitted so there is nothing for the client to connect to. I could introduce some
mechanism for attempting to report early errors in server start up by perhaps
writing to /tmp but it may all just get rather arcane.

If you would like to be able to start the server in a truly "read only" way I
can do that easily, I think it should be a configuration file parameter though
so that administrators have to choose it.

What do you think ?
