I'm working with embedded software and we have to use COW containers pretty often.
[...] Can you describe a typical or example use case, from your experience, where COW is necessary? My own perspective: I've generally thought that, for typical container usage, COW is unnecessary, in the sense that it gives no performance benefit (and, if anything, a performance hit) given disciplined coding practices; COW is complicated to implement correctly and constrains your design; and, simply put, COW is a pessimism. It might be useful in exceptional circumstances, but certainly, I would think, far less frequently than "pretty often". But I'm open and curious to hear others' experiences. - Jeff
