My proposal is that you would have to call
        JvCreateJavaVM (NULL);
before JvAttachCurrentThread.  See my example program.  JvRunMain
also calls JvCreateJavaVM.

I'm unsure whether JvCreateJavaVM should do PROCESS_GCJ_PROPERTIES.

Where are the shutdown hooks currently handled?  I didn't see them
in the code I changed.

Currently, FirstThread contains the getMain methods to find the
main method of a jar.  It seemed easier to keep that as Java code,
but it might be reasonable to merge it with some other class.
