I grabbed apache-tomcat-9.0.52.tar.gz from
https://downloads.apache.org/tomcat/tomcat-9/v9.0.52/bin/apache-tomcat-9.0.52.tar.gz
I unpacked it to /opt/apache-tomcat-9.0.52.tar.gz.
I uninstalled tomcat9 (purged, and rm -rf /var/lib/tomcat/webapps)
I tweaked CATALINA_HOME and JRE_HOME appropriately.

I ran $CATALINA_HOME/bin/start.sh.  As root, which clearly was a mistake.
I thought it would su, but clearly I should start it as mortal user.
Perhaps there is a better script, but clearly the tomcat package took care of that.
(I wouldn't want to run it as root in production at all)

Before fixing that mistake, I notice:

I've done nothing.  No deploy.  Of course, the manager is included, so
perhaps it is compiling or deploying that?

So, 169M of ~4G used.  No swapping.  Lots of ram free.
