File in the attached changeset. (don't show keystroke events)

do: "HandMorph showEvents: true"

quickly, press A, press B, release A, release B.

you should see these flash by the top-left corner of the screen,
and on Cog, this is what you see:

    [keyDown 'a']
    [keyDown 'b']
    [keyUp 'a']
    [keyUp 'b']

on the official VMs, you instead see this:

    [keyDown 'a']
    [keyDown 'b']
    [keyUp 'b']

(you can of course use any two keyboard buttons)

It's an issue on mac and linux at least. Not sure about windows
