A patch to read() multiple times

Some joysticks with high sampling rate need to be read() more fast,
otherwise it delay user inputs due to internal queue.
Especially, an app that issues SDL_PollEvent() not so frequent, such as:

while ( ! done ) {
usleep(10*1000); // <-- some delay
while ( SDL_PollEvent(&event) ) {
:
}
}

It is solved by read()-ing multiple times at once.
(I think this is safe because of O_NONBLOCK mode)
