[boost] [serialization] exception-safety of container-serialization

Dear All,

I have just added serialization to Boost.Ptr container.
I briefly discussed an issue with Robert, namely
that the current implementation calls clear() before
reading the new values.

The alternative is to provide roll-back guarantee by default
by creating a local container and swap() in the end.
By default this would temporarily use more memory.

IMO we should go for the strong guarantee.
Any thoughts?
