I did not get much response (well none actually) about this issue. But I
went out today and run the doctests. They finished, with failures (see
the end), but more to the point, look at the state of the machine.

Total: 150 processes, 358 lwps, load averages: 8.70, 8.70, 8.79
There's 3 maxima processes still running, when there should be non. For
some reason they are not using a high percentage of CPU time, but the
load average is very high. I've had this before, and will have to find
out what it was (it would not surprise me if it Sage related, as the
machine was fine when I went out earlier). But now you can see, there
are maxima processes running. Tests are failing, but not killing the
processes.
Here are the failures. I had increased the timeout to 1800 second (half
an hour) just in case any that were timing out were doing so as my
machine is not sufficiently fast.

However, an ERROR occurred in the Distributed Sage unit tests.
Please see /export/home/drkirkby/.sage//tmp/test.log for the complete
log from this test.
Does anyone have any idea why the maxima processes are not being killed?
It's difficult to doctest Sage if doing so causes such a huge load, due
to processes not being killed.
