Actually, this loses something in the translation, since the
word here is "trap" not "address". A trap is an unimplemented
68000 instruction.
This only works for stack-based calls, which are normally limited
to the toolbox. For example, if MacMETH doesn't provide assembler,
and doesn't provide direct access to the file manager, device
manager, and memory manager, you're SOOL.
