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.
