blackfin fpga programming: if client socket killed or failure while writing to flash, only file pointer closed but fpga not asked to pick up from flash and client exception thrown. If all good and picking up from flash takes more than 10s, it will also throw exception in client. Client exception will prevent a reboot and hence allowing user to try to flash again.
