Something like this:

[
  [
    [ 60 seconds asDelay wait.
      (FileDirectory default fileOrDirectoryExists: '/var/squeak/save.squeak')
        ifTrue: [ SmalltalkImage current snapshot: true andQuit: false ]
    ] on: Error do: [ :error | error asDebugEmail ]
  ] repeat
] forkAt: Processor systemBackgroundPriority.
Project uiProcess suspend.

Based on a script from Ramon Leon.
