I would rather revert the change entirely until it is implemented
properly.

Also, I am strongly of the opinion that this is a mis-use of the
alternative call interface.  It was never intended to be used for
things that can make real function calls.

You can add a million clobbers, or a trampoline, it's still using a
facility in a manner for which it was not designed.

This means a new interface with a new name and with capabilities
explicitly supporting this case are in order.

Thanks.
