michael@0 1 // Bug 717104 - Unreachable debuggee globals should not keep their debuggers
michael@0 2 // alive. The loop is to defeat conservative stack scanning; if the same stack
michael@0 3 // locations are used each time through the loop, at least three of the
michael@0 4 // debuggers should be collected.
