Mathias Agopian 0a8cd0689a fix a race condition in undoDequeue(), where 'tail' could be computed incorrectly. ... in the undoDequeue() case, 'tail' was recalculated from 'available' and 'head' however there was a race between this and retireAndLock(), which could cause 'tail' to be recalculated wrongly. the interesting thing though is that retireAndLock() shouldn't have any impact on the value of 'tail', which is client-side only attribute. we fix the race by saving the value of 'tail' before dequeue() and restore it in the case of undoDequeue(), since we know it doesn't depend on retireAndLock().
