Tomcat JVM not exiting

[Jeff Birkner]

When I call shutdown on Tomcat after using it as a remote cache, the
Tomcat JVM does not exit.

I am using JCS 1.3 
The remote cache is running on a Linux server in Tomcat 5.5.9 using a
disk cache.  
When I call shutdown on Tomcat, everything seems to work properly.   I
see the shutdown logged and the keys get written to disk.

The problem is that the Tomcat process sticks around unless it is
explicitly killed.  I believe that the problem stems from the thread:
