Is this right (Process>>interruptName:)

I just saw this code in Process>>interruptName: and I'm wondering how 
it's supposed to work:

    projectProcess == Processor activeProcess
                                                ifTrue: [projectProcess suspend]

Unless I'm missing something (which is very possible), this would 
suspend the execution of the method altogether and not bring up a 
debugger.

Is there some magic here that I need to learn about?

Thanks,
