Not sure. Now that I think of it, it makes sense that if I go to sleep,
a deadlock is not sudenly going to appear while I am asleep. If a new
process causes a deadlock, the new process that causes it will see it.
I did not check when I went to sleep because I thought it may be too
cpu-intensive to do checking on every sleep, but now that I remember it,
it may be very trivial in cpu time to do the check on every sleep.
I recommend changing it to do it just before every sleep. Let me know
if you want me to make the change.
