Not sure what "to throw at" means in the context of C++ exceptions.
(I'm afraid we are deviating from the original topic, though.)

With exception-throwing comes stack-unwinding, so the thrower
has to be on top of the call stack, not someone outside (or even
in another thread).

The point really is that we want a means to interrupt an otherwise
non-interruptible (i.e. blocking) call, so this requires support
from the system layer.
