Well, I was pretty sure... if the server is idle and I
request a single jsp suddenly a half-dozen (more or less,
depending on the complexity of the page) tomcat threads are
active for no discernable reason. I used to have log
entries that I think also supported my interpretation, but
I'm not finding them now.
So I added a valve to one of the <Host>s:
<Valve className="org.apache.catalina.valves.AccessLogValve"
directory="logs" prefix="com_example_access_log." suffix=".txt"
pattern="common" />
and after that I didn't see the multiple tomcat4:javas
running on each access to jsps on that host, although I
still did on the other hosts. So I added AccessLogValves to
the other <Host>s and now I don't see the behavior.

I still think it's weird, though.
(BTW: I upgraded to libapache-mod-jk to 3.3a-4woody1, and
this is Linux kernel version 2.4.20.)
