traverse node on change of "required" state;
wenzelm [Mon, 29 Jul 2013 18:59:58 +0200] rev 52775
keep memo_exec execution running, which is important to cancel goal forks eventually;
run as nested worker task to keep main group valid, even after cancelation of removed subgroups;
do not memoize interrupt, but absorb it silently in main execution;
Goal.purge_futures: rough sanity check of group status;
wenzelm [Mon, 29 Jul 2013 16:52:04 +0200] rev 52774
maintain explicit execution frontier: avoid conflict with former task via static dependency;
start execution immediate after assignment, to keep frontier simple;
wenzelm [Mon, 29 Jul 2013 16:01:05 +0200] rev 52773
afford higher execution priority by default: defer proofs and thus stretch parallelism over whole document;
wenzelm [Mon, 29 Jul 2013 15:59:47 +0200] rev 52772
clarified conditions for node traversal;
