Using lazy vectors in library mode

[Jeroen Demeyer <J.Demeyer@UGent.be>]

I have a question about using "lazy vectors" such as ell structures.

It seems to me that the usual programming model manipulating avma may 
lead to memory leaks with such structures. So one should call obj_free() 
on an elliptic curve before resetting avma.

However, it seems difficult to automate this: as far as I know, a 
program cannot know that ellinit() returns a lazy vector. So I wonder 
how GP and GP2C deal with this. I am asking this in the context of the 
Python interface, where this is probably giving memory leaks currently.
