Hi.
Can't find any option for suspending  Prochannel modules when there is no audio on the input.  (tested on sonar X2 Producer X2a) 
I'm have Cubase 6.5, Cubase 7 Artist and Ableton Live 8 and Studio One 2.5 Producer.
All of this DAW's are able to suspend native modules!
Cubase 7 also is able to suspend 3rdParty VST3.  

how bout using the off button to turn them off?

Would bypass be the same as sleep?

No, I'm not going to say it.

ProChannel modules take up exactly zero processing when there is no audio present on a track. You can verify this for yourself (just like I did) by doing this:

1. Create an audio track in an empty project.
2. Enable whatever modules you'd like...I used the EQ and CA-2A
3. clone that track a number of times....I did 100
4. press play and watch your CPU meters.

Again, as someone said....  The off button

As Razorwit pointed out, PC modules use no resources  whatsoever when they're switched off.
 
As for third party plugins - what do you mean by suspend?  They all have off buttons too.  In fact, hit "E" on your qwerty and they all switch off.
 
Have we missed something?

1.Create an audio track in an empty project.
2.Load some audio content on it.
3.Enable 5 instances of the BREVERB module on it - CPU ~0%
4.Play audio track to enable prochannel input port - CPU ~15%
5.Wait the end of the audio data and check CPU when project is playing but audio data is finished   - CPU ~15% !!!! 

you've got 5 instances of breverb on it???  how long are you letting it play when it's 15% because with 5 verbs you must have inaudible tails from hell going on.
