If you are just writing on a line by line basis, OS buffering should  
mitigate the need to do anything special, as long as you don't mind  
have lines interleaved from different daemons.

e.g.

a whole line from daemon1
a whole line from daemon1
a whole line from daemon2
a whole line from daemon1
a whole line from daemon1
