Correct.

It could potentially lead to a situation where you
cannot do your sim realtime anymore. But I think that
the avg computer can simulate reasonably accurate, faster
than realtime, provided that the physics problem is not
too complex. (even when it's slowed down by rendering once
in a while).

Hmm... that doesn't sound right.
You have to measure wall-clock time, if you want
an accurate 9.8 m/s*s acceleration in falling objects,
for instance, don't you?
