Though I guess in this instance the Jeff> lifetime is limited and we don't have to worry about the GC system? It's the latter. The patch doesn't really change whether or not the elements of the array are visible to the GC. It just changes how the vector is managed -- from manual use of new/delete to automatic via vector. The plugins do need to interface with the GC, but this is done by registering GC'able objects in a global hash table that is manually marked; see the 'preserve' and 'mark' methods on the plugin context objects. thanks, Tom
