After the GUI programs reported success, execute command "sync"
in a shell and wait until it is done.


If you really want to write unbuffered:
There is an i/o mode named "Direct I/O", which is not well-deemed
by the kernel developers. Your mileage may vary.
Program "dd" has an option "oflag=direct".
C function open(2) has flag O_DIRECT. 


Have a nice day :)
