Seems to be working fine!  The additional debug info is a big help.

That only leaves the ucontext stuff to test yet which is what I really need
since it allows stack overflow checking to be done on an exception basis
(i.e when it occurs) and not before every and every access which should
speed up the jdk interpreter significantly.

Thanks,

Kevin
