It seems to me like you would then have the issue that an attacker could "trick" the system into the less secure mode just by causing a few short sleeps. You could try to mitigate that too, but then the odds are it would come back to bite you at some point in the future.

If various people in these comments think they have worthwhile alternative ideas for this, that might be a good thread to jump in on and propose patches or different algorithms or whatever else.
