When you turn on an output, do you set a flag and then check it to see the output's status before turning the output on again? 

Or do you just turn it on without checking?

Is setting a flag a good way to speed up the program and avoid tying up the network with unnecessary communications to I/O?

Or does it just add a lot of extra variables and decision blocks that make debugging and maintenance harder?
