Re: [ns] Dynamic objects

[Haobo Yu <haoboy@isi.edu>]

Nothing prevents you from doing that, just like you can new/delete objects
in otcl. But you should be careful how the deleted objects would interact
with other objects, especially if there're pending events scheduled when 
you delete the target object for the events.

Furthermore, you should not new/delete split objects from C++; they should
always be done from otcl so that correct initialization is done. 

Hope this helps.
