Doh! Why didn't I remember the "thread dump" option on the system tray
monitor. Of course, I don't remember now whether it showed Tomcat as running
or down. The services MMC showed "Stopping" and the tomcat5.exe was still
running, but I can't remember what the status said in the system tray. Will do
that next time.

Yep. I'm not sure why there are so many hits on Google for "tomcat
thread dump" that aren't on the Tomcat site, but most of them only work
in one environment or another.
I'm a contributor to this Wiki page, which should help you in almost any
case. If you can't get it working in your environment, let us know and
we'll add another section to help.
