In a nutshell, the latter: the documentation should be updated in a few 
places, sorry.

Consider that a lot of changes happened in that area and for 4.0 a new 
allocator (not the "trivial" new-based allocator, not the old HP/SGI 
pool_allocator) will be the default, optimized for MT applications. As 
you can see a preliminary version of it is also available for 3.4.x 
(called __mt_alloc in the docs).

Thanks for your patience,
Paolo.
