Details
Flag values as read as soon we actually use a context slot in the trace. Similarly, flag all slots we write. If we either read or write a slot, import it (it has to be a legal value even if we update it along one path of the tree only but then enter, take some other path, side exit and then try to write back). If we never touch the value, don't write it out.
