I made the following change
<Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
port="8009" minProcessors="5" maxProcessors="100"
enableLookups="true" redirectPort="8443"
acceptCount="100" debug="0" connectionTimeout="20000"
useURIValidationHack="false"
protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"/>
And it appears to have fixed the lock-up problem at least. The problem wasn't in tomcat in my estimation, the apache/mod_jk side was holding onto the connection and not allowing the next request to use it. The timeout kills off the connections that are being held onto by apache and so no lockups. I think this is only a temporary kludge/fix, but for the other people who were having the same problem, try this for now. Thanks for everyone's help.

ps.
I also upgraded from 4.1.12 to 4.1.17 in my debugging process though that didn't solve the problem in and of itself.

Also, you can see messsages about their starting up in cataling_log.YYYY-MM-DD.txt (where YYYY-MM-DD is the date). And it may be correct that they are not closed/stopped once they're started.
