Ah right.

Reading more into logs and code, my guess is that there is not enough
Cpu.pull() calls to get jobs from the coaster service:

$ grep pull coasters.log | grep -v Later | cat -n
    62  2009-07-23 11:08:09,813-0500 INFO  Cpu 0723-021156-000001:51 pull
    63  2009-07-23 11:08:09,814-0500 INFO  Cpu 0723-021156-000001:52 pull
    64  2009-07-23 11:08:09,841-0500 INFO  Cpu 0723-021156-000001:53 pull
    65  2009-07-23 11:08:09,918-0500 INFO  Cpu 0723-021156-000001:54 pull
    66  2009-07-23 11:08:09,968-0500 INFO  Cpu 0723-021156-000001:55 pull
    67  2009-07-23 11:12:06,079-0500 INFO  Cpu 0723-021156-000001:56 pull

These pull() calls get invoked in the bunch of cpus in the pullthread
correct?  I'll read up on pullthreads and try to figure things out.
