Greetings: I was investigating a library called Nedmalloc which seems to offer exactly the functionality I was looking for. It's a local heap allocator, very flexible, clean, but most importantly portable. I have added the nedmalloc.h, nedmalloc.c and malloc.c.h in my sandbox under boost/detail and example/. The dedicated example tlh_pool_test1.cpp works in Windows but I haven't included the interface into the new tlh_pool.hpp file yet. Furthermore if_from() will need to be implemented because Nedmalloc doesn't offer some lookup over the list of segments to match a pointer to. There is a function called segment_holding() that will need to be wrapped by some mspace_holding(). Any pool gurus are welcome to criticize Nedmalloc or anything else before I use it. Regards, -Phil
