2013-07-29 ago clarified conditions for node traversal;
2013-07-29 ago tuned;

2013-07-20 ago option editor_execution_priority;
2013-07-15 ago more careful termination of removed execs, leaving running execs undisturbed;

2013-07-11 ago global management of command execution fragments;

2013-07-11 ago re-assign prints of unchanged eval only -- avoid crash of new_exec;
2013-07-11 ago tuned -- refrain from odd optimization;
2013-07-11 ago tuned;
2013-07-10 ago tuned start_execution: avoid sleep on worker thread;
2013-07-10 ago clarified Command.print: update old prints here;
2013-07-09 ago produce print_execs assignment earlier during last_common phase (referring to current command_id, not prev);
2013-07-09 ago more formal type assign_update: avoid duplicate results and redundant update of global State.execs;
