+Bug 4889: No connections are accepted after ECONNABORTED
+
+Ignore ECONNABORTED errors when accepting connections. These "client
+decided not to wait for accept(2)" errors do not indicate a problem with
+the listening socket and should not lead to listening socket closure.
+
+Also polished errno checking code for non-ignored errors.
+
+Also documented a bug that prevents TcpAcceptor::acceptOne() from
+stopping to listen on non-ignored accept errors.
+
+Also documented ENFILE and EMFILE mishandling.
