Dear Boosters,

The documentation of intrusive_ptr says

"As a general rule, if it isn't obvious whether intrusive_ptr better
fits your needs than shared_ptr, try a shared_ptr-based design first."

but does not explain why.

If the classes involved are all my own and deriving them all from a base class
that implements reference-counting is not a problem, what are some reasons
to prefer shared_ptr to intrusive_ptr?

Thanks,

Ilya
