checkpoint: working on reworking debugger implementation ... need to support multiple open debuggers
multiple open debuggers now supported issues with running unwind blocks on close appear to be addressed ... took opportunity to toss some of the unused methods like the halos ... the nodes are now stashed in /tmp/debug/<process oop>...still need to toss node on window exit
clean up some client-side issues involving terminating processes correctly when debugger is closed
remove logging ... remove process node in /tmp/debug
