right.  I don't see any problem with the custom deleter..
If a custom deleter is specified for a shared pointer,  I would
expect it works as it always does.

More of a problem is the allocator.  Allocation is currently
a detail in the serialization library.  As such, I'm not sure
how easy to override it would be.  On the other hand, since
the STL collections have an allocator parameter, it might
be that this is already addressed automatically by the
serialization library.  This would require more research
into how the library allocates new object.  I realize I wrote
this code, but it was a number of years ago and I don't
remember how it works.
