std::terminate() isn't just for unhandled exceptions, though (eg. it's
also called for unjoined threads). And this still kind of is an
unhandled exception anyway.

Using std::terminate() allows hooking std::set_terminate() to trigger
logging or minidump/coredump, which can be useful. (abort() can be
similarly intercepted via SIGABRT, but it's a more restricted context.)

Or to put it another way: std::terminate() is C++; abort() is C. It
seems wrong to use the C-based termination method in a C++ context.
