Correct me if I'm wrong, but I don't believe you've ever tried this.
The dispatch table ends at sysTrapLastTrapNumber. There are no entries
for libraries, which is why SysGetTrapAddress() and SysSetTrapAddress()
don't work for library functions.
To catch things out beyond sysTrapLastTrapNumber (i.e. the library traps 0xA800 and
beyond),
you would wind up rewriting the trap exception vector handler. This is a proposition
I would
describe as hairy at best. Not to mention the performance hit.
