My objects can delete themselves in two cases:

1) in the constructor, when they realize they cannot handle the job 
they are supposed to do, because they cannot allocate the resources 
required,

2) in a member function, when they finish their job and free their 
resources.

I guess that in the constructor I should throw an exception, instead 
of trying to delete the object.  So the first case is resolved.

The second case is tricky.  I could keep a container of smart pointers 
to my objects, and delete objects by removing the pointer from the 
container.  The problem is that this removal should be initialized by 
the object itself, i.e., in a member function a pointer is removed 
from the container, but then that function operates on an object that 
was just deleted.
