Perhaps it is our ears, rather than the machine, that tolerate the clipping.

Again, maybe our ears just tolerate it and we don't notice. If a peak is
just barely into positive territory, then the clipping doesn't last long,
it isn't very sharp, and it isn't very deep.
Also, Hannes Rohde pointed out,

In other words, "OVER" isn't necessarily over? Yet digital recording at
unity gain and playback will never make "OVER" light up. OK, so the OVER
light could be disabled during playback, but during digital recording at
unity gain (given that it can light during digital recording at positive
gain)?

Wish we could average your CDs with mine, Richard. My problem is that so
many are mastered too softly. When I record them to MD it is very tedious to
set the gain to make the peak exactly touch 0 dB (because it is so tedious
and imprecise to find the peak), so I settle for getting it above -1 dB.
