af67eaaea5 Correct the logic in mvfreesize -- lost spans are not accounted as free. only sum the free space in the spans in checking varieties, otherwise just return the cached sum.

38614c785e Make shield assertions robust against deep checking -- when shieldcover is called from shieldraise there is one unsynced segment that has not yet been queued. record this fact in a new queuepending flag in the shield structure. 
Remove incorrect shield assertion "shield->depth == 0 || shield->suspended" -- depth may be increased without suspending the mutator if the segment did not need protecting.
