//Storing shared pointers in boost pool allocators
//tl;dr It just works (tm)
//
//* If a lot of smallish objects are being allocated & freed a pool allocator
//can speed things up by specialising in allocating exactly that size of
//object.
//
//* If pointer lifetimes need to be managed with reference counting,
//std::shared_ptr can wrap an object to provide safe reference counting.
