What is the underlying thread system?  Does it incorporate pthreads,
or some other thing?

In a Sun virtual machine environment, garbage collection can run at
any arbitrary time, and there is nothing that the application can do
to prevent this.  In the case of timing-critical applications, the
user is at a loss, and thus there can be no determinism in that
environment.  I am looking to see how well gcj can perform as an
avenue for real time deterministic java applications.
