[Help-smalltalk] DynamicVariable in a Continuation

[Derek Zhou]

Hi All,
It looks like the sematic of DynamicVariable changed not very long ago; it
was based on Notification, but it now just uses a ProcessVariable. Here is a
simple testcase: 

DynamicVariable subclass: Seed [
    ].
Eval [
    |b g1 g2|
    b := [:v | v + Seed value].
    g1 := Generator on: [ :g |
        |v|
        v := 0.
        Seed use: 2 during: [
            [ g yield: v.
              v := b value: v ] repeat ]].
    g2 := Generator on: [ :g |
        |v|
        v := 0.
        Seed use: 3 during: [
            [ g yield: v.
              v := b value: v ] repeat ]].
    Transcript nextPutAll: '%1 %2 %3 %4' % {
        g1 next.
        g2 next.
        g1 next.
        g2 next}; nl.
]

It used to yield "0 0 2 3" but yields "0 0 3 3" now. I'd think "0 0 2 3" is
the correct answer; the documantion specifically mentioned stackframes so
the stackframes hopping from the Continuation should affect the variable,
right?
