Load. By this you mean the operation of taking a bit-pattern in RAM
and putting it into a register? So, you can calculate 0/0, get a
signalling NaN, and then save that into a memory variable, all without
it trapping; and then it traps when you next perform an operation on
that number?

Apologies, this is getting quite off-topic and away from Python.
