If tcp_write returns ERR_MEM then it's not a fatal error but instead means the caller should retry the write later on (and this is what lwIP's netconn API does). This fixes problems where a TCP send would raise OSError(ENOMEM) in situations where the TCP/IP stack is under heavy load. See eg issues adafruit#1897 and adafruit#1971.
