Sleep time is set to default--seconds(1).

No errors or warnings that I can see.  It looks like CPU use is pretty
consistently in the 60%-100% range no matter what is going on.  And none
of the lists I'm serving get that much traffic--I haven't done an exact
analysis, but I don't think we're talking about more than a few emails
per hour.  Most of the lists are a few dozen people, just a couple are a
few hundred.

Let me know what else I can try to track down the problem.
