Going off on a tangent, are there other interfaces where reuse may be
possible such as JVMPI, JPDA, and the wire protocols for those... if the
hooks into the free JVMs are somewhat standard?  Essentially Sun wrapped
the native interfaces like JVMPI with Java in JPDA which made the tasks
of writing profilers or debuggers somewhat easier.  So these Java
wrappers should be the same if written to the C interfaces that
pre-existed JPDA but then all the JVMs need to support those
interfaces.  To what extent should Classpath provide parts of the
debugging/profiling solution?
