I am confused about "work that was put off" vs committing. My script
was doing a commit right after the CVS import, and you are right
about the massive times required to shut tomcat down. But in my tests
the time taken to do the commit was under a second, yet I had to allow
300secs for tomcat shutdown. Also I dont have any duplicates. So 
what sort of work was being done at shutdown that was not being done
by a commit? Optimise!

Thanks for the all the help.
