Just to recap, these are the three problem areas that still produce
latencies over 500 usec on my machine.

journal_clean_checkpoint_list
rt_garbage_collect
vga console

I have found that the latter does not require switching back and forth
to X; anything that produces a lot of console output can trigger 500
usec latencies.
