Bug description:
"Pointer.h/intrusive_ptr_base" class is too heavy-weight (at least on unix), it
uses pthread mutex for every increment/decrement. And since this mutex is
static (Thread::mtx), it leads to bad concurrency even for independent
intrusive pointers.
Patch attached, which uses portable atomic reference counters from boost.
It uses boost::detail::atomic_count from shared_ptr, so it may theoretically
change in future (since it is in detail), but I doubt it will.
