Igor, don't you think that it is possible to make hack here?!

1) V4MD is single-thread. Always.

2) so we can prepare

    a) one Vtable object which live long time
    b) one VField object which live long time

Just assign to them I_Table* or I_Field*
And return them as result?

No, this will not works :-(
Because we cannot differ if user have made it as tmp object
Or he have store reference to this object...

------
Well, have you investigate if something can be improved in e.g. Xtra
creation?

May be we cache some pointers to interfaces?
So next time we will use cached values instead of QueryInterface() ?

Ok, this is not the main target now Igor.
Just keep in mind that later we can think here for optimization.
