Under normal circumstances, this is true. However, in @swegner's case, he doesn't care about two-way communications. So, the delay is not going to hurt anything since his board is going to sleep anyway.
@swegner - I have cleaned up your sketch, simplifying and moving all of your special logic to the bottom of the setup() routine. The loop() routine, in this example will never be called, as it really serves no purpose based on how you're using these microcontrollers with deepSleep().
