/**
*  SAT Server includes a scheduler of it's own to simplify
*  client request handling code. All active object leaves are
*  handled in function Error(). The behaviour of Error()
*  depends on whether there is an outstanding client request
*  or not: it will tell the client the reason for inability
*  to handle the client request. It will also panic the
*  client if the descriptor passed to the server was malformed.
*  Finally, a panic is raised if the error does not originate
*  from the server itself.
