I want to assess some implementation details, some which can be expected to be common among the major VM implemetatons (for default I am referring to the Win32 implementation). A good programmer is interested to know what he really invokes when allocating a new object. For example the minimum data size that an instance of a type consumes on the heap. Perhaps the question can be transformed into "what is the minimum size of data allocation blocks on the heap?". I have looked into the VM documents but found nothing about this because it is undefined. - So does somebody know about what the real practice is? Or where can I go to look for more information? Thanks! - Vander
