but let me rephrase it.

So the problem is:
During the boot process, when the rc scripts are printing messages (for
example "Creating and/or trimming log files"), if I turn on the scroll
lock, then (1) the messages are not printed and are permanently lost,
and (2) the system waits for backgrounded (shell script) sleep calls to
end before proceeding.
Here's a test case. Insert the following text into /etc/rc.d/bgfsck:
echo TURN ON THE SCROLL LOCK NOW
sleep 4
echo HI THERE
sleep 30 &
echo HI THERE
During boot, when you see the "TURN ON THE SCROLL LOCK NOW" message,
turn on the scroll lock. Wait for 5 seconds, then turn off the scroll
lock. Confirm that the script sleeps for another ~30 seconds, and that
neither "HI THERE" message are ever printed.
