Don't know much about it, but I read more than a year ago
that some company had a JVM with "guaranteed deterministic"
timing.

How about a garbage collector in a lower priority
task that runs continuosly for some percentage of
CPU time instead of hogging the machine only when
desperately needed?

(Another thing that would be nice is a JVM that is
a shared library or resident in the OS or something,
instead of--this is for multi-user environments, BTW--
having every Java program running its own copy of the JVM.)
