    Modified Files:
    src/conio/x_events.c src/syncterm/CHANGES
    Log Message:
    Fix a potential race between drawing and discarding last buffer.

    If the last is freed while the screen is being updated, and the use
    after free bug is not detected, corruption could occur resulting in
    bad areas of the screen that persists until the window gets an
    expose event again, or the impacted pixels are updated again.

    Possibly fixes an issue reported by nelgin via IRC.
