+"Another issue I've noticed is trying to pass a table with a function
+that uses closures in it as a global variable into a new lane.  This
+causes a segmentation fault and it appears to be related to the
+luaG_inter_move function near line 835-836 or so in lanes.c, but I
+haven't investigated further.
+e.g. { globals = { data = 1, func = function() useclosurehere() end } }"
