 For many functions inserting pointers into a pointer container, the
 documentation says that they provide strong exception-safety
 guarantee while they are actually not. Instead, they perform delete
 on the passed pointer if an exception is thrown.

 I propose the wording like this; "When an exception is thrown,
 nothing happens except performing delete x."

 Note that replacing it with "basic guarantee" is over relaxing.
 One should be able to assume the contents of the container are
 unchanged when an exception is thrown.

 This was first posted on the mailing list.
