Invoke New Handler

[Frederick Gotham]

I see that the Standard provides "set_new_handler", but I don't see an
equivalent "get_new_handler" anywhere. Do we have to do something like the
following?

#include <new>

inline void (*GetCurrentNewHandler())()
{
struct Dummy { static void DummyFunc() {} };

void (*const p)() = std::set_new_handler(Dummy:ummyFunc);

std::set_new_handler(p);

return p;
}

inline void InvokeCurrentNewHandler()
{
GetCurrentNewHandler()();
}

I think GetCurrentNewHandler might no be thread-safe though, in the event
that "new" would be used in another thread in between the "set_new_handler"
calls.
