makeClusterPSOCK() will try tries times, (3 times by default), if makeNodePSOCK() throws an error. However, some errors are not worth the retry, e.g. invalid argument values.
Alternative, take the complementary approach and create a specific "PSOCKConnectionError" error class that is the only type of error for which we should retry. This can be done by upgrading the error objects thrown in
