What about the VM change for a cleanup? That is just to wait for multiple
things to happen?

    nextTimed: timeout [
        "Wait for an object up to timeout seconds"
        <category: 'accessing'>
        | delay expired result |

        delay := Delay forSeconds: timeout.
        expired := delay timedWaitOn: valueReady.

        expired ifTrue: [
            "Raise some kind of exception"

        queueSem critical: [result := queue removeFirst].

so something like the above for SharedQueue would be acceptable upstream? Or
should I keep it as an extension?
