Just to report that I have run the synchronized soak test using 5
threads and 10,000,000 loops on

AlphaServer 4X00 5/400 4MB, 4 CPUs

Running
OpenVMS 7.3-1

java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition
Fast VM (build 1.4.0-1, build J2SDK.v.1.4.0:01/10/2003-09:47, native
threads, jit_140)

This took about 8 minutes.

The unsynchronized test fails rapidly with just 2 threads:
