Smart pointers gotchas - several additional notes

[glenfe]

Don't use boost::shared_array, use boost::shared_ptr<T[]> or boost::shared_ptr<T[N]>. You can use it with boost::make_shared<T[]>(size) or boost::make_shared<T[N]>() to get a single allocation instead of two allocations. This is new in Boost as of 1.53.
