[pygccxml-development] performance: make_flatten vs. _make_flatten_generator

[Allen B. <al...@vr...>]

Roman:

It looks like about 1/3 of the time is now being spent inside 
proceed_single in make_flatten. 

Is there any reason I shouldn't be able to use _make_flatten_generator 
instead of make_flatten so I can remove the performance hit of 
allocating the memory for such a large list every time make_flatten is 
called?
