I had no look at you lib but this sounds like the file descriptor
you are writing to is not connected to a tty or the buffering
of it has been changed to fully buffered.  stdio functions buffer
data.  If the fd is in line buffered mode (default for tty-fds)
it emits the data if a \n is seen.  In full buffered (default for
anything else) it waits until the buffer is really full (1-4kb).

And, the buffer is of course flushed when the program exits...
