"Select debug app" and "Wait for debugger" are new feature in Jelly Bean, does someone know how to use these new features?

I found the answer here: http://developer.android.com/tools/debugging/debugging-devtools.html
Lets you select the application to debug. You do not need to set this to attach a debugger, but setting this value has two effects:
- It will prevent Android from throwing an error if you pause on a breakpoint for a long time while debugging.
- It will enable you to select the Wait for Debugger option to pause application startup until your debugger attaches (described next).

It is a mystery to me also, but I'll share my experience. I cannot see that these options change the phone's behavior. Regardless of the settings I choose, the Galaxy Nexus behaves like my older phones that do not have the settings.
"Waiting for debugger" is a dialog that I see whenever I start running an app from Eclipse. It stays up for a while, and then my app starts running. This has been the case since I started Android development, and it still works that way on my old and new devices, regardless of the setting.
If I click on "Select Debug App", it allows me to select an app from the already installed apps on my phone that allow debugging, which are the apps that I wrote myself.
On my Galaxy Nexus it does not matter whether I select "Nothing" or one of my debuggable apps, I can still debug any app from Eclipse. I cannot even see a difference in time it takes to load an app over the ADB connection.
