Yes. To summarize a long story, allocators are a work in progress and we are
currently concentrating on yet another one, called mt_allocator. Unfortunately,
we haven't been able to forward port to a new framework in time for 3.4.0 the 
traditional pool allocator and, to be safe, we chosen the "trivial" new-based
allocator as the default. Then, for ABI stability we couldn't change that
default anymore for the next 3.4.x releases. However, for 3.4.2 and newer you
can always configure it yourself at build time to obtain a behavior very
similar to that of 3.3.x allocator. Thanks, Paolo.
