How about using SoftReference to store _large_ or some session data?
It must add additional overhead due to data re-retrieval needed in
case it has been collected, but at least its guaranteed that you will

Tomcat can quite happily use port 80; what else do you need httpd for?

SSL as a protocol is not designed to allow for this sort of

There can be hidden dependencies on native code. For example, JDBC
