In a discussion with a customer about the new Java Plug-In, a mechanism for forcing an individual applet into its own JVM instance was requested. While specifying JVM command-line arguments such as -Xmx will increase the chances of an applet getting its own JVM instance, there might be situations where a given applet really doesn't want to run in the same JVM with any others. This is a simple change to make so we should try to support it in the initial release.
