stdout buffering

[rennergade]

In NaCl, STDOUT isn't flushing automatically when it encounters a newline which seems to be the POSIX standard. It would be nice to no where the NaCl handles that and to fix it.

I think its probably worth finally trying to resolve this one, I've been putting it out because it takes a decent amount of investigation and hasn't ever been a blocking issue. It would be nice to not have to use fflush() calls though to make sure things are synchronized.

@kuzeyardabulut this might be good for you to investigate. I think it probably entails delving into libc.
