You might want to have a version of that command that doesn't schedule the removal to gc, but rather removes all the object parts by itself. Otherwise, you're just going to flood the gc. You'll need to iterate through all the objects, and for each object you'll need to remove all of it's rados objects (starting with the tail, then the head). Removal of each rados object can be done asynchronously, but you'll need to throttle the operations, not send everything to the osds at once (which will be impossible, as the objecter will throttle the requests anyway, which will lead to a high memory consumption).
