I'd say the benefits is very small compared to the development efforts
required, and the portability effects outweights all of it by far.

It is more important to get clustering of small allocations to cut down
on the memory overhead for large pools and further reduce fragmentation.
The actual resource overhead (both CPU and memory) of using malloc() to
allocate the memory areas is minimal, and malloc is portable to all
platforms which are candidates for Squid.
