The 'LD_ASSUME_KERNEL' setting was needed with Red Hat 9. I'm on FC3 now and
it seems to be working fine *without* having to specify LD_ASSUME_KERNEL.

Actually, I could swear (though I have no metrics) that FC3 is running my
Java stuff much faster than RH9 did with a forced LD_ASSUME_KERNEL setting.

Your suggestion to avoid using the Java 'new' keyword is interesting, and I
believe I know what you're getting at - but I think you should expand on it,
perhaps with some specific pointers. It seems to leave too much to the
imagination at the moment :-)

As an example, in my application all the 'action objects' that handle
requests are singletons - instantiated at start-up, and handed out as needed
at runtime. But you have to be careful with that approach - instance
variables are a complete no-no.
