If they can ever realize they were bitten by this feature.

Can we go for different tradeoff?

In console_unlock(), if you detect too much work, print "Too many
messages to print, %d bytes delayed" and wake up kernel thread.

You still get the latency, and people bitten by this feature will at
least get fair warning.
