I do the following:

   (Delay forSeconds: 10) wait.
   Project uiProcess suspend.
] fork.
SmalltalkImage current snapshot: true andQuit: true

While writing this I must confess that I'm not 100% sure if this works.
I assume the forked block gets also suspend and continues after starting
the saved image which would lead to the suspend action.
