That's a whole lot more heavyweight --- you'd have to transport the exception
into the thread in a type-safe manner in order to throw it. It's not
impossible --- you can copy the passed exception into a buffer along with a
function to throw it, and pass that over to the thread --- but it's
conceptually a lot more complicated.
