C++ does. just override std::operator new() and you're done.
in truth, since most of these language-specific allocators ultimately
devolve to calling C's malloc(), you can do an awful lot by just
including a malloc() implementation as part of the host SDK.
i routinely link most of my apps against libhoard, an amazingly fast
multithread-aware malloc implementation. by making it the last library
linked before hitting the standards, i pretty much ensure that
everything that allocates from the heap goes through libhoard.
that said, i think that mandating explicit host-based allocation is
the best way to handle the worst cases. people doing C++ STL operations in
the main "process" callback will have to understand why they cause
dropouts very occasionally, and come to grips with STL Allocator
objects :)
