- if it is a waste of time even trying to get a connaction. Just because this method
doesn't throw an exception it doesn't guarantee that one will be available. There is a slight
risk that we might tell the client to give up when a connection could become available in the next few
milliseconds but our policy is to refuse connections quickly when overloaded.
