1 Worker= 1 JVM?

[GASNIER Lise]

Hi,
Judging by the Tomcat-Apache How-to and its Multiple Tomcat JVMs section, 
1 instance of Tomcat= 1 JVM ("you have to be running two separate instances
of Tomcat, hence the "multiple JVMs").
And the Tomcat workers.properties doc says  "a tomcat worker is a tomcat
instance".
So, 1 worker = 1JVM...
But when running Tomcat with a workerlist composed of two workers, I can see
only one JVM (using TaskInfo).
Can someone tell me if this assertion is correct: 1 worker= 1 JVM.

thanks a lot,
Lise
