When a call in the server raises an exception that is passed back to

the client, don't log it at the ERROR level.  If it really was a
disaster, the client should log it.  But if the client was expecting
the exception, the esrver shouldn't get all upset about it.  Change
this to the INFO level.  (When it *is* considered an error by the
client, it's useful to be able to see the server-side traceback in the
log.)
